Value Collection R52001071 Self Drilling Screw 1/4 in

Product Description

The VALUE COLLECTION R52001071 is a self drilling screw designed for fast, reliable fastening without a pre-drilled pilot hole. It features a 1/4 inch hex washer head driven by a standard hex drive tool. The shank measures 2-1/2 inches in length under the head. The No. 3 drill point bores through material and threads simultaneously, reducing installation time on metal-to-metal and metal-to-substrate applications. Constructed from Grade 1016-1024 steel with a zinc-plated finish, the screw resists corrosion in typical indoor and light outdoor environments. This fastener is suited for sheet metal, light structural, and panel attachment work performed by electricians, HVAC technicians, and general mechanical contractors.

This self drilling screw is commonly used in HVAC ductwork assembly, electrical enclosure mounting, metal stud framing, and equipment panel installation. The hex washer head provides a broad bearing surface that distributes clamping load and resists pull-through on thinner gauge sheet metal. The zinc-plated finish makes it appropriate for indoor applications and sheltered outdoor installations where moderate corrosion resistance is needed. Sold in multiples of 50 per order with a package quantity of 1.

Key Features

• No. 3 drill point eliminates need for a pilot hole in compatible sheet metal gauges
• 1/4 inch hex washer head provides wide bearing surface and positive drive engagement
• 2-1/2 inch length under head accommodates thicker substrate stacks
• Grade 1016-1024 steel construction for reliable tensile and shear strength
• Zinc-plated finish provides corrosion resistance for indoor and light outdoor use
• Hex drive compatible with standard 1/4 inch hex bit drivers and nut drivers

Compatibility

Designed as a general-purpose OEM-style replacement or new-installation self drilling screw for sheet metal, light structural, and mechanical equipment panel applications requiring a 1/4 inch hex washer head fastener with a No. 3 drill point.

Installation Notes

Installation is typically performed by HVAC technicians, electricians, or sheet metal workers using a 1/4 inch hex bit driver or nut driver with a variable-speed drill or impact driver. Ensure the substrate material gauge is within the rated capacity of a No. 3 drill point before driving. Do not overdrive the screw, as the washer head can strip or deform thin gauge metal. Follow applicable mechanical codes and equipment manufacturer guidelines when fastening enclosures or structural components.
