Value Collection R52001077 Self Drilling Screw 50 Pack

Product Description

The VALUE COLLECTION R52001077 is a 1/4 inch hex washer head self drilling screw built for fast, reliable fastening in metal-to-metal and metal-to-wood applications. Featuring a No. 3 drill point, this screw drills its own pilot hole and taps its own thread in a single operation, eliminating the need for pre-drilling. The hex drive head accepts a standard hex bit driver for quick installation with a power tool. Manufactured from Grade AISI 1016-1024 carbon steel with a zinc-plated finish, it delivers corrosion resistance suitable for general-purpose interior and sheltered exterior use. Sold in a minimum order quantity of 50 screws.

This screw is suited for light structural, HVAC ductwork, metal framing, electrical enclosure, and general sheet metal assembly applications. The 3 inch length under head provides solid bite through thicker material stacks or when fastening through insulation and metal panels. The zinc-plated finish makes it a common choice for interior mechanical room work and light commercial construction where moderate corrosion resistance is required. Installers in HVAC, plumbing rough-in, and electrical trades routinely use self drilling screws of this type for securing sheet metal components and light gauge framing members.

Compatibility

Designed as a general-purpose OEM-style replacement or stock fastener for self drilling screw applications in light gauge steel, sheet metal panels, and metal framing assemblies.

Installation Notes

Installation is performed with a power drill or impact driver fitted with a 1/4 inch hex bit. De-energize and lock out any electrical equipment before fastening near live panels or enclosures. Apply consistent axial pressure to allow the drill point to engage before the screw begins to thread, preventing walking on smooth metal surfaces. Follow applicable building codes and manufacturer fastener schedules when used in structural or fire-rated assemblies.
