Description

Industrial fasteners designed for metal fabrication, structural steel, and industrial enclosures. Self-drilling screws enable direct fastening into carbon steel without pilot holes, improving installation speed and clamp integrity.

Specs

  • Dimensions: Diameter 1/4 inch; Length 2 inches
  • Drive Type: Hex Washer Head
  • Material Grade: Carbon Steel
  • Thread Type: 1/4-20 UNC

Features

  • Self-drilling design: Eliminates need for pilot holes when fastening into carbon steel sheets and components; reduces installation time in metal fabrication, HVAC, and electrical panel assembly.
  • Hex Washer Head: Provides flush seating with surface sealing and even load distribution; improves resistance to pull-out under vibration.
  • Point Type 5: Optimized geometry for efficient penetration in carbon steel, enabling fast, consistent starting and reduced cam-out.
  • Material: Carbon Steel offers adequate shear and tensile strength for standard industrial fastening scenarios; compatible with common coatings per finish specifications.
  • Applications: Suitable for metal-to-metal joints in industrial equipment housings, structural framing, ductwork, and panel mounting where 1/4-20 thread pattern is required.
  • Install considerations: Use appropriate driver torque and drilling parameters to avoid over-tightening and material deformation; ensure alignment and pilot hole avoidance in thin sheets.
