Value Collection R50000251 Self Drilling Screw 1/4 in

Product Description

The VALUE COLLECTION R50000251 is a 1/4 inch self drilling screw designed for fast, reliable fastening without the need for a pre-drilled pilot hole. Built from steel with a zinc-plated finish for corrosion resistance, this screw features a hex washer head driven by a standard hex drive. The No. 3 drill point cuts through metal and structural materials cleanly. With a 3/4 inch length under head, it is suited for thin-gauge sheet metal connections common in HVAC ductwork, equipment panels, metal framing, and general sheet metal fabrication work. Installation is handled by HVAC technicians, sheet metal workers, and general tradespeople.

This self drilling screw is used in light commercial and residential applications where sheet metal fastening is required. Typical install scenarios include attaching duct sections, securing equipment enclosures, fastening metal brackets to structural members, and general sheet metal assembly. The hex washer head provides a broad bearing surface that distributes load and resists pull-through. The zinc coating offers baseline protection against moisture and oxidation in conditioned or semi-exposed environments. Sold in minimum order quantities of 100 units per order.

Compatibility

Designed as an OEM-style replacement and general-use fastener for sheet metal assemblies, HVAC ductwork, equipment enclosures, and metal framing applications requiring a 1/4 inch self drilling screw with a hex washer head.

Installation Notes

Installation is typically performed by HVAC technicians or sheet metal workers using a hex bit driver or nut driver set to appropriate speed. Power down all equipment and de-energize panels before fastening screws near electrical components. Avoid overdriving, which can strip the drill point or distort the base material. Follow applicable mechanical and sheet metal codes for fastener spacing and edge distance.
