Machine Screws

Raptor Supplies offers a wide range of machine screws from brands like APM Hexseal, Disco, Fabory, Grainger, Lisle, Micro Plastics, Texas Pneumatic Tools & Temper-Pruf Screws. They are designed to secure panels and parts through existing tapped holes on electronic equipment, engines and large machines.

Features

  • These machine screws consist of a head and a fully threaded shank.
  • The shank features exterior threading for allowing the screw to be driven into tapped holes with interior threading.
  • Grainger machine screws provide tensile strength up to 101526 psi and are available in head diameters ranging from 1 mm to 0.717 inches.
  • Micro-Plastics machine screws are available in polycarbonate, nylon & 18-8 stainless steel variants to ensure corrosion and impact resistance.

Frequently Asked Questions

What is the difference between machine screws and bolts?

  • Machine screws have a slotted head, whereas bolts have a hex head.
  • To install a machine screw, place a flat-heat or Philips head screwdriver into the slotted head and turn it. The screw can be removed by turning the screwdriver in the opposite direction (anti-clockwise).
  • Bolts feature a hex head instead of a slotted head. For installing a bolt, place a hex socket over the head and turn it.
  • Machine screws are generally smaller than bolts. Machine screws are less than 1 inch long, whereas bolts come in a variety of sizes, with some of them being over 2 inches long.

What standards do these machine screws comply with?

These machine screws adhere to AN, ASME, ASTM, CSA, DIN, EHEDG, FDA, Federal Specifications, IFI, ISO, JIS, Military Specifications, MS90728-10, NAS, SAE and UL standards.
