Value Collection TKHWI0-800750-2-050B 8 Hex Washer Head Screw

Product Description

The VALUE COLLECTION TKHWI0-800750-2-050B is a No. 8 hex washer head self drilling screw designed for fast, reliable fastening in light metal and sheet metal applications. Featuring a hex drive and a No. 2 drill point, this screw drills its own pilot hole and threads in a single operation, eliminating the need for pre-drilling. The 3/4-inch length under head suits thin-gauge metal assemblies common in HVAC ductwork, metal framing, and electrical enclosure work. Manufactured from AISI 1016/1024 grade steel with a zinc-plated finish for corrosion resistance, this screw meets ASME B18.6.3 and SAE J78 standards. Sold in a minimum order quantity of 50 pieces.

This self drilling screw is well suited for residential and light commercial trade work where sheet metal connections require a secure mechanical fastener without pre-drilling. Common applications include HVAC duct assembly, metal stud framing, electrical panel and enclosure mounting, and general sheet metal fabrication. The No. 2 drill point is rated for thinner gauge metal, making this screw a practical choice for ductwork seams, junction box covers, and similar light-duty metal-to-metal connections encountered in routine service and installation work.

Key Features

• No. 2 drill point self-taps and drills in one step — no pilot hole required
• Hex washer head with hex drive for positive tool engagement and high torque transfer
• 3/4-inch length under head suits thin sheet metal and duct applications
• AISI 1016/1024 steel construction meets ASME B18.6.3 and SAE J78 standards
• Zinc-plated finish provides basic corrosion resistance for indoor metal assemblies
• Sold in multiples of 50 for job-site and service-truck stocking

Compatibility

Designed as a standard No. 8 self drilling screw for light-gauge sheet metal applications where a No. 2 drill point and hex washer head are specified.

Installation Notes

Installation is typically performed by HVAC technicians, sheet metal workers, or electricians using a hex-drive bit with a power drill or impact driver. Power down and de-energize any equipment before fastening into electrical enclosures or panels in accordance with NFPA 70 (NEC) lockout/tagout procedures. Do not overdrive the screw — hex washer head designs are susceptible to stripping if excessive torque is applied. Ensure the base metal gauge is appropriate for a No. 2 drill point before installation.
