Value Collection TKHWI-1000750-3-100BX No. 10 Self Drilling Screw

Product Description

The VALUE COLLECTION TKHWI-1000750-3-100BX is a No. 10 self-drilling screw designed for fast, reliable fastening without a pre-drilled pilot hole. Featuring a hex washer head with a hex drive, this screw provides high torque transfer and a built-in bearing surface that seats flush against the workpiece. Constructed from steel with a zinc-plated finish for corrosion resistance, it measures 3/4 inches in length under the head. The No. 3 drill point bites through light-gauge steel and similar substrates without walking or slipping. Sold in a minimum order quantity of 100 pieces per box.

This screw is suited for light-gauge sheet metal assembly, HVAC ductwork fabrication, electrical enclosure mounting, and general metal-to-metal fastening applications. The hex washer head style is common in trade applications where a driver socket or nut driver is used rather than a bit tip alone. The zinc plating provides adequate corrosion resistance for interior and protected exterior installations. Contractors and tradespeople working in HVAC, electrical, and light construction will find this screw a standard choice for sheet metal work.

Key Features

• No. 3 drill point self-drills through light-gauge steel without a pilot hole
• Hex washer head provides a wide bearing surface and reduces pull-through
• Hex drive accepts standard nut drivers and hex-drive bits for power tool use
• Steel construction with zinc-plated finish for corrosion resistance
• 3/4 inch length under head suits thin-gauge metal-to-metal fastening
• Sold in 100-piece increments for job-site and shop use

Compatibility

Designed as a standard No. 10 self-drilling screw for light-gauge sheet metal fastening applications including HVAC ductwork, electrical enclosures, and general metal framing assemblies.

Installation Notes

Installation is performed with a nut driver or hex-drive bit matched to the hex washer head. Power down or de-energize any electrical panels or HVAC systems before fastening into enclosures or ductwork. Do not overdrive the screw, as stripping the drill point or deforming the washer head will reduce holding strength. Follow applicable codes, including SMACNA duct construction standards where required for HVAC applications.
