Value Collection MSC-74125436 Self Drilling Screw 12

Product Description

The VALUE COLLECTION MSC-74125436 is a No. 12 self drilling screw with a hex washer head and hex drive, manufactured from Grade 410 stainless steel. It features a No. 3 drill point, allowing it to penetrate metal substrates without a pre-drilled pilot hole. The 1-inch length under head measurement makes it suited for light-gauge fastening applications. Grade 410 stainless steel provides corrosion resistance combined with the hardness required for reliable self-drilling performance. This screw is installed by electricians, HVAC technicians, and sheet metal mechanics working with light-gauge metal framing, ductwork, enclosures, and related assemblies.

This screw is used in light commercial and residential applications where a self-starting fastener is needed in metal-to-metal or metal-to-substrate connections. The hex washer head distributes clamping load evenly across the fastened surface, while the hex drive provides positive engagement with a standard hex driver bit. Typical applications include HVAC duct assembly, electrical enclosure mounting, metal framing, and equipment panel attachment. This item is sold individually with a minimum order quantity of 100 units.

Key Features

• No. 3 drill point eliminates the need for a pilot hole in light-gauge metal
• Grade 410 stainless steel construction for corrosion resistance and hardness
• Hex washer head provides broad clamping surface and positive seating
• Hex drive for secure bit engagement and reduced cam-out during installation
• 1-inch length under head for light-gauge fastening applications
• Inch measurement system for straightforward sizing in standard trade applications

Compatibility

Designed as an OEM-style replacement or standard-supply fastener for No. 12 self drilling screw applications in light-gauge metal assemblies typical of HVAC, electrical, and sheet metal work.

Installation Notes

Installation is performed by sheet metal mechanics, HVAC technicians, or electricians using a standard hex driver bit in a power screwdriver or drill. Power down and de-energize all equipment before fastening near live electrical components. Apply consistent axial pressure during driving to allow the drill point to engage cleanly without walking. Do not overdrive, as stainless steel fasteners can shear at high torque if run in with excessive speed.
