Value Collection 1464KW Self Drilling Screw 1/4 in Hex Washer

Product Description

The VALUE COLLECTION 1464KW is a 1/4 inch self drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. It features a hex washer head with a hex drive and a Number 3 drill point that eliminates the need for a pre-drilled pilot hole. The screw measures 4 inches in length under the head and is manufactured from Grade 1016-1024 steel with a zinc-plated finish for corrosion resistance. It is sized for use with a standard 7/16 inch hex driver bit. This fastener meets AISI 1016, ASME B18.6.3, and SAE J78 standards, making it a code-appropriate choice for structural and mechanical assembly work performed by HVAC technicians, electricians, and sheet metal fabricators.

This screw is suited for applications requiring a secure, load-bearing fastener in light-gauge steel framing, ductwork, electrical enclosures, equipment panels, and similar trade installations. The hex washer head provides a broad bearing surface that resists pull-through, and the self-drilling point speeds up installation by combining drilling and threading in a single step. The 4 inch under-head length accommodates thicker material stacks or layered assemblies common in mechanical and electrical rough-in work.

Key Features

• Number 3 drill point eliminates pilot hole drilling in light to medium gauge steel
• Hex washer head provides wide bearing surface and resistance to pull-through
• Hex drive accepts standard 7/16 inch driver bits for fast installation
• Grade 1016-1024 steel construction for strength in structural fastening
• Zinc-plated finish adds corrosion resistance in typical indoor mechanical environments
• Meets AISI 1016, ASME B18.6.3, and SAE J78 standards

Compatibility

Designed as a standard inch-series self drilling fastener suitable for light-gauge steel framing, sheet metal assemblies, and mechanical equipment enclosures where a 1/4 inch diameter, 4 inch length under head fastener is specified.

Installation Notes

Installation is performed with a hex driver or impact driver fitted with a 7/16 inch hex bit. Ensure all power is removed from electrical enclosures and all equipment is de-energized before fastening into panels or live assemblies. Self drilling screws generate metal shavings during installation — clear debris from sensitive components to prevent shorts or equipment damage. Follow applicable code requirements, including NEC guidelines when fastening within or adjacent to electrical enclosures.
