Value Collection R55000140 No. 8 Self Drilling Screw

Product Description

The VALUE COLLECTION R55000140 is a No. 8 self drilling screw designed for fastening applications where a separate pilot hole is not required. Featuring a hex washer head and hex drive, this screw provides positive bit engagement and a built-in washer-style bearing surface to distribute load and resist pull-through. The No. 2 drill point allows the fastener to cut through material and thread in a single operation. Constructed from Grade 410 stainless steel, it delivers corrosion resistance suitable for demanding indoor and outdoor environments. The length under head measures 1-3/4 inches. These screws are sold in quantities of 100 and are a standard choice for sheet metal, light structural, and HVAC duct fabrication work.

Self drilling screws of this type are used across a wide range of trade applications including HVAC duct assembly, metal stud framing, equipment enclosure fabrication, and light-gauge sheet metal attachment. The No. 2 drill point is suited for thinner gauge steel and aluminum substrates. HVAC technicians, sheet metal workers, and general contractors regularly use this fastener where speed and reliable thread engagement in metal are priorities.

Key Features

• No. 2 drill point eliminates the need for a separate pilot hole in light-gauge metal
• Hex washer head provides a built-in seating surface to reduce pull-through
• Hex drive ensures positive bit engagement and reduces cam-out
• Grade 410 stainless steel construction for corrosion resistance
• 1-3/4 inch length under head suits a variety of sheet metal thicknesses
• Inch measurement system; No. 8 screw size is a common trade standard

Compatibility

Designed as a standard No. 8 self drilling screw for use in light-gauge sheet metal, HVAC ductwork, and similar metal fastening applications where a No. 2 drill point and hex washer head configuration are specified.

Installation Notes

Installation is performed with a hex driver bit matched to the fastener head size; a variable-speed drill or impact driver with a depth-sensitive bit holder is recommended to avoid overdriving. Confirm the substrate gauge is within the rated capacity of a No. 2 drill point before fastening. When working on HVAC systems or electrical enclosures, de-energize and lock out the equipment before performing any sheet metal work in the vicinity of live components.
