Description

Type A Self Tapping Sheet Metal Screws with an Indented Hex Washer Head enable fast, secure fastening into sheet metal. The unslotted drive and steel zinc & bake finish deliver reliable torque control and corrosion protection in professional assemblies.

Specs

  • Dimensions: Diameter 5/16 inches; Length 3 inches
  • Finish: Zinc & Bake
  • Drive type: Unslotted
  • Material grade: Steel

Features

  • Self tapping capability: Creates mating threads in sheet metal, enabling assembly without pre-threaded holes or tapping operations.
  • Head design: Indented Hex Washer Head distributes load across the joint surface, reducing pull-through in soft metals.
  • Drive engagement: Unslotted drive interface requires compatible hex drive tooling, providing robust torque transfer and reducing risk of cam-out when used with appropriate bits.
  • Finish and corrosion protection: Zinc plating with bake coating offers a corrosion-resistance barrier suitable for indoor and mildly humid environments.
  • Material suitability: Steel base provides higher strength relative to nonferrous alloys for structural sheet metal closures and enclosures.
  • Typical applications: Automotive interior panels, electrical enclosures, appliance housings, HVAC ductwork, metal cabinets.
  • Installation guidance: Ensure sheet metal thickness and hole pitch align with screw dimensions; consider pilot hole size where recommended by design standards for self tapping screws.
