Stewart Fastener J0808BRPWTZ Tek Screw No.8 X 1/2 in 100pk

Product Description

The STEWART FASTENER J0808BRPWTZ is a No. 8 x 1/2 inch modified truss head Phillips drive self-drilling tek screw, sold in a pack of 100. The modified truss head delivers a wider, lower-profile bearing surface than a standard pan head, distributing clamping load across a broader area. The self-drilling point eliminates the need for a pilot hole, allowing faster installation into light-gauge sheet metal, metal framing, and similar substrates. These screws are suited for HVAC ductwork fabrication, electrical enclosure assembly, metal stud framing, and general sheet metal fastening tasks common in the mechanical trades.

This fastener is intended for light-gauge metal-to-metal or metal-to-substrate fastening in both residential and commercial construction and service applications. The compact 1/2 inch length makes it well suited for thin-material assemblies where fastener protrusion on the back side must be minimized. HVAC installers, sheet metal workers, and electricians commonly use this screw size for duct connections, junction box covers, and panel trim attachment.

Key Features

• Self-drilling tek point eliminates pilot hole drilling in light-gauge metal
• Modified truss head provides a wide, low-profile bearing surface for flush or near-flush seating
• Phillips drive compatible with standard No. 2 Phillips bits
• No. 8 x 1/2 inch size suits thin-material and short-depth fastening applications
• Pack of 100 supports job-site quantity needs without per-unit handling

Compatibility

Designed as a general-purpose self-drilling screw for light-gauge sheet metal and metal framing applications common in HVAC, electrical, and mechanical trade work.

Installation Notes

A No. 2 Phillips bit in a variable-speed drill or screw gun is the standard tool for this fastener. Set the clutch or use controlled pressure to avoid overdriving the shallow 1/2 inch shank, which can strip the material or snap the head. Confirm substrate gauge is within the rated drilling capacity of a standard tek point before driving. Follow applicable building codes and manufacturer guidelines for fastener spacing on structural or rated assemblies.
