Nylon 6/6 Machine Screw, Fillister Head, Slotted Drive, #10-32, 7/16" Length (Pack of 100)

Nylon 6/6 Machine Screw, Fillister Head, Slotted Drive, #10-32, 7/16" 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
  • Fillister head for high torque and good hold-down strength
  • Driven by a flat-bladed driver
  • 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.

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).

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. 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. 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.

Stainless Steel Machine Screw, Fillister Head, Slotted Drive, #5-40, 5/8" Length (Pack of 100) Feature

  • Machine Screws are often used with nuts or driven into tapped holes
  • Stainless Steel is suitable where formability and cost are important considerations
  • Fillister head for high torque and good hold-down strength
  • 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.

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).  Another common naming convention for Austenitic Stainless Steels are 18/8, 18/10, 18/0, etc. where the 18 refers to the % of Chromium and 8 to the % of Nickel contained in the material.

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.

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.

Fillister head for high torque and good hold-down strength

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.
