Peco Fasteners tp-8x1/2tpm Hex Washer Head Screw 1000 Pack

Product Description

The PECO FASTENERS tp-8x1/2tpm is a size 8 by 1/2 inch hex washer head tapping screw sold in a 1000-piece pack. This fastener features twin lead threads, which reduce driving torque and allow faster installation compared to single-lead designs. The screw body is actually 9/16 inches long, providing greater thread engagement than the nominal 1/2 inch callout suggests. These screws are used across HVAC, sheet metal, and general trade assembly work where a self-tapping fastener with a hex washer head is required. Installation is handled by HVAC technicians, sheet metal workers, and general trade professionals.

The tp-8x1/2tpm is well suited for light-gauge sheet metal applications common in HVAC ductwork fabrication, equipment cabinets, and metal panel assembly. The hex washer head provides a wide bearing surface and allows for drive with a standard hex bit or socket. The twin lead thread design is particularly useful in production or field settings where high-volume fastening is performed and reducing fatigue from driving resistance matters.

Key Features

• Twin lead threads reduce driving torque for faster, easier installation
• Actual body length of 9/16 inches provides greater thread engagement than nominal size
• Hex washer head offers wide bearing surface and hex bit compatibility
• Self-tapping point eliminates the need for pre-drilling in light-gauge sheet metal
• 1000-piece pack suited for production and high-volume field work

Compatibility

Designed as a standard size 8 by 1/2 inch hex washer head tapping screw for use in light-gauge sheet metal applications typical of HVAC equipment, ductwork, and metal enclosure assembly.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, or qualified trade professionals using a hex bit driver or nut driver sized for the hex washer head. Ensure the substrate material is appropriate for self-tapping fasteners before driving. Do not overdrive, as this can strip the thread engagement in thin-gauge material. Follow applicable sheet metal and mechanical codes for fastener spacing and pull-out requirements.
