Value Collection R52001007 Self Drilling Screw No. 12 Hex Washer

Product Description

The VALUE COLLECTION R52001007 is a No. 12 self drilling screw designed for metal-to-metal and metal-to-substrate fastening in trade and industrial applications. It features a hex washer head driven by a hex driver and a No. 3 drill point that bores its own pilot hole as it seats. The fastener measures 1-3/4 inches in length under the head and is manufactured from Grade 1016-1024 steel with a zinc-plated finish for corrosion resistance in standard indoor and light-duty outdoor environments. HVAC, electrical, and sheet metal tradespeople regularly use this screw type when assembling ductwork, panels, and equipment enclosures where speed and a clean, load-distributing washer head are required.

This screw is suited for residential and commercial trade work where a self-starting fastener eliminates pre-drilling steps. Common applications include securing HVAC sheet metal panels, electrical junction box covers, light-gauge steel framing attachments, and general metal fabrication. The hex washer head distributes clamping load across a wide bearing surface, reducing pull-through in thin-gauge stock. This item is sold in a minimum order quantity of 100 units per order.

Key Features

• No. 3 drill point drills its own pilot hole, eliminating a separate drilling step
• Hex washer head provides a broad bearing surface to reduce pull-through in sheet metal
• Hex drive accepts standard 5/16-inch hex driver bits for power tool installation
• Grade 1016-1024 steel construction meets AISI, ASME B18.6.3, and SAE J78 standards
• Zinc-plated finish provides corrosion resistance for standard service environments
• 1-3/4 inch length under head accommodates common sheet metal and light structural stack-ups

Compatibility

Designed as an OEM-style replacement and general-use self drilling screw suitable for light-gauge sheet metal and standard metal panel fastening applications in HVAC, electrical, and sheet metal trades.

Installation Notes

Self drilling screws of this type are installed by licensed sheet metal workers, HVAC technicians, and electricians using a power drill or impact driver fitted with a 5/16-inch hex bit. De-energize and lock out any electrical or mechanical equipment before fastening panels or covers per OSHA lockout-tagout requirements. Apply consistent axial pressure when driving to allow the drill point to penetrate before the threads engage. Do not overdrive — overtightening strips the hole in thin-gauge material and reduces clamping force.
