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 303 contains 0.15% carbon, along with traces of sulfur and phosphorus which makes this a free machining alloy. Free machining refers to the ability to cut and finish the materials without heavy wear on the machining tools. Tensile Strength is 35000 psi (pounds per square inch). Passivation helps prevent corrosion in certain stainless steels by removing surface impurities that can be caused by machining or forming processes. These impurities block the normally occurring formation of a protective oxide coating on the steel.

Binding head provides a large surface area for extra surface contact under the head

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. 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.

Aluminum Machine Screw, Round Head, Slotted Drive, #8-32, 5/8" Length (Pack of 50) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Aluminum is suitable for applications where weight and corrosion resistance are primary considerations
  • Round head style for a finished appearance
  • Driven by a flat-bladed driver
  • 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.

Aluminum is composed of bauxite and alumina. Pure (99%) Aluminum melts at 1220 degrees Fahrenheit. It has approximately two-thirds of the thermal and electrical conductivity of copper. Aluminum has a high strength to weight ratio and is resistant to tarnishing and corrosion. Aluminum is an extremely versatile material, it may be cast or wrought, it is available in a wide range of alloys and tempers, and it accepts many types of surface finishes, including anodizing. Aluminum is easy to machine, solder and weld.

Round head fasteners have a dome-shaped head. An older style of head, it is typically used when replacing existing round-head fasteners where an exact match is desired. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

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. 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.

Brass Machine Screw, Flat Head, Phillips Drive, #8-32, 1-1/2" Length (Pack of 100) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Brass is suitable where corrosion resistance is a primary consideration
  • 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.

Brass is rust proof, corrosion resistant and polishes to a rich, golden color. Brass is easily soldered and brazed and accepts plating readily. The typical composition is 70% Copper and 30% Zinc. Strength increases with a higher percentage of Zinc.

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.

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. 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.

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.

Acetal resins are characterized by their strength, stiffness, and hardness, and are stable over a wide range of temperatures, humidity, environments, and stress. Acetal has a low coefficient of friction, and absorbs little water, minimizing the effect of moisture on its physical properties. Acetal resists neutral oils, grease, petroleum-based fuels, many organic solvents, alkalis, oxidizing agents and acids, both organic and inorganic. Compared to Nylon 6/6, Acetal is harder and has better water resistance, but lower impact strength and abrasion resistance. Acetal is translucent off white in color.

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. Common applications for slotted screws include woodworking, although the drive style is not designed to be used with power drivers.

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.

Nylon 6/6 Machine Screw, Flat Head, Phillips Drive, M2.5-0.45, 6mm 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
  • 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.

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).

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.
