Description

Type A self-tapping sheet metal screws are designed to form threads in thin metal when driven. This variant features a hex washer head, unslotted drive, and 18/8 stainless steel construction in a 5/16 x 3/4 size.

Specs

  • Dimensions: 5/16 x 3/4"
  • Drive Type: Unslotted Drive
  • Material Grade: 18/8 Stainless Steel (304)
  • Thread Type: Type A Self-Tapping

Features

  • Self-tapping capability: Forms internal threads in sheet metal without pre-drilling, enabling streamlined installation.
  • Hex Washer Head: Large bearing surface distributes load and reduces pull-through in thin substrates.
  • Unslotted Drive: Requires hex or Allen driver; provides controlled torque and compatibility with tight assemblies.
  • Corrosion resistance: 304-grade stainless steel offers robust resistance to rust and staining in typical indoor and outdoor environments.
  • Material compatibility: Suitable for HVAC, appliance fabrication, automotive trim, and electrical enclosures where stainless fasteners are preferred.
  • Size-specific considerations: 5/16 diameter, 3/4 length balances thread engagement with material thickness for secure fastening.
