Polycarbonate Machine Screw, Pan Head, Phillips Drive, #10-32, 7/8" Length (Pack of 100)

Polycarbonate Machine Screw, Pan Head, Phillips Drive, #10-32, 7/8" Length (Pack of 100) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Polycarbonate is suitable where high impact strength and hardness are primary considerations
  • Pan head allows for higher tightening torques
  • Phillips drive is designed to cam out under too much torque
  • Fine threads tap better into harder materials and thin walls, and are stronger in tension than coarse threads
Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Polycarbonate is one of the toughest, most dimensionally stable thermoplastics over a wide temperature range. Impact Strength, as measured by the Izod impact test method (which measures force required to break material), is 17 pounds per foot. This is significantly tougher than standard Nylon 6/6, which is rated at 3 pounds per foot. Polycarbonate is a relatively non-hydroscopic material; it will only absorb extremely low amounts of water even after extended exposure. Polycarbonate is very resistant to greases, oils, detergents, aliphatic hydrocarbons, most mineral acids, and the higher alcohols. It is does not perform well with chlorinated hydrocarbons, and most aromatic solvents, esters, and ketones. Polycarbonate has a blue tinted transparency with 89% light transmission. Tensile strength is approximately 10,000 psi (pounds per square inch).

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

A threaded fastener's size name includes information about the major external diameter, followed by the threads per inch, which indicates if it is coarse or fine. Fine threads are preferable when working with harder materials or when threading into a thin material. They are also stronger in tension than coarse threads, and generally provide higher shear strengths.

Nylon 6/6 Machine Screw, Pan Head, Phillips Drive, M5-0.8, 10mm Length (Pack of 100) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Nylon 6/6 is suitable where non-conductivity, corrosion resistance, and cost are important considerations
  • Pan head allows for higher tightening torques
  • Phillips drive is designed to cam out under too much torque
  • Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Nylon 6/6 is a general purpose thermoplastic with outstanding resistance to organic chemicals, acids and alkalis. Nylon wears well against other surfaces; it is readily machinable and may be milled, turned and cut with conventional machine tools. It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

A threaded fastener's size name includes information about the major external diameter (in millimeters), followed by the thread pitch (millimeters per thread), which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings.

Polypropylene is a thermoplastic which is autoclavable (meaning that it can be sterilized using steam), and is non-hydroscopic (it won't absorb water even after extended periods of contact). Polypropylene has excellent chemical resistance to dilute acids, concentrated acids (except oxidizing acids), alkalis, alcohols, detergents, and water. Polypropylene resists aromatic hydrocarbons, chlorinated hydrocarbons, greases, and oils at room temperature. Maximum operating temperature is 212 degrees Fahrenheit. Polypropylene has a low co-efficient of friction and a high dielectric strength (meaning it operates well as an insulator). Polypropylene has approximately half the tensile strength and impact strength of Nylon 6/6. The tensile strength of Polypropylene is 5000 psi (pounds per square inch). Impact Strength, as measured by the Izod impact test method (which measures force required to break material) is 0.5 pounds per foot.

Stainless Steel 316 Machine Screw, Flat Head, Phillips Drive, 1/4"-20, 2" Length (Pack of 25) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Stainless Steel 316 is suitable for use where Stainless Steel 304 does not provide enough corrosion resistance
  • Flat head style allows fastener to sit flush to the surface
  • Phillips drive is designed to cam out under too much torque
  • Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Stainless steels are used for their corrosion resistance, high-temperature strength, scaling resistance, and low-temperature toughness. These properties account for their extremely wide use in practically every industry. Austenitic Stainless Steels are alloys of iron and carbon that contain between 16% and 30% Chromium, a maximum of 0.15% carbon, along with Nickel (or Manganese), and other alloying elements. The chromium, which helps develop a passive surface oxide film, provides corrosion resistance in stainless steels. Austenitic Stainless Steels are designated by a 3 digit SAE Stainless Steel Grade beginning with the number 3 (e.g. 304, 316).

Stainless Steel 316 has a higher nickel and molybdenum content than most Austenitic stainless steels which means that this material offers more corrosion resistance without giving up strength or hardness. Tensile strength is 35,000 psi (pounds per square inch).

Flat head fasteners are designed to fit flush to the surface when used with countersunk holes. Length is measured from the top of the head. The Phillips drive style was originally designed so that the driver would slip out under extreme torque, preventing over-tightening and damage to the fastener or the material.

  • Fillister head for high torque and good hold-down strength
  • Phillips drive is designed to cam out under too much torque
  • Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

It does exhibit some dimensional swelling in wet applications which should be taken into account with its use. Tensile strength of this material is 12,000 psi (pounds per square inch).

Fillister head fasteners are considered an improvement over round head equivalents - the smaller head creates more downward pressure for a given torque level and the thicker head plus deeper drive slot allows higher torque levels to be generated.

Machine Screws, also referred to as Machine Bolts, are often used with nuts or driven into tapped holes. They come in a variety of head types and drive styles, but are generally available in smaller sizes.

Steels are designated by a 4 number SAE Steel grade.  The first two digits indicate the primary materials used to form the steel.  The last 2 digits identify the percentage of carbon for the alloy (in hundredths).  The steel used in these fasteners has a tensile strength ranging from 100,000 to 150,000 psi (pounds per square inch).  Zinc Plating helps to prevent corrosion.

Pan head fasteners have a low, large cylindrical head with a high rounded top edge for higher tightening torques - these fasteners are often recommended to replace older head styles such as round, binding, or truss-head where possible.
