Limited Time 1/4 X 2-1/2″ Type AB Self Tapping Sheet Metal Screws Truss Head Six Lobe Drive Steel Zinc & Bake (700/Pkg.)

Type AB Self Tapping Sheet Metal Screws with a Truss Head and Six Lobed Drive are designed for secure metal-to-metal joints in sheet metal assemblies. Steel construction with Zinc & Bake finish provides corrosion resistance and reliable drive performance in demanding environments.

Specs

Dimensions: 1/4″ diameter x 2-1/2″ length

Drive type: Six Lobed Drive

Finish: Zinc plated with bake finish

Material: Steel

Thread type: Self tapping

Features

Six Lobed Drive: High torque acceptance with reduced tool cam-out during metal fastening, improving installation reliability in power tool driven applications.

Truss Head: Broad bearing surface distributes clamping load to minimize pull-through in thin sheet metals and soft substrates.

Self Tapping thread type: Creates mating threads in base metal without pre-drilling, accelerating assembly workflows for sheet metal housings and enclosures.

Finish: Zinc plating with bake coating delivers enhanced corrosion resistance and wear protection for interior and semi-exterior environments.

Material: Steel provides robust shear strength and structural integrity for fasteners in typical sheet metal applications.

Applications: Suitable for HVAC ductwork, electrical enclosures, appliance cabinets, metal panels, and light structural assemblies requiring reliable self tapping fasteners.

Performance benefits: Improved drive retention, load distribution, and ease of installation in repeated-use or high-torque scenarios compared to standard pan-head or flat-head self tapping screws.
