Value Collection MSC-74125329 No. 8 Self Drilling Screw

Product Description

The VALUE COLLECTION MSC-74125329 is a No. 8 self drilling screw designed for fastening applications that require the screw to drill its own pilot hole without a pre-drilled substrate. Featuring a hex washer head and hex drive, it delivers reliable torque transfer and a broad bearing surface that resists pull-through. The screw measures 3/4 inches in length under the head and is manufactured from Grade 410 stainless steel, providing corrosion resistance suitable for both interior and exterior service environments. A No. 2 drill point enables clean penetration into light-gauge metal and similar materials without pre-drilling.

This screw is commonly used in HVAC ductwork assembly, sheet metal fabrication, roofing, and light structural fastening tasks. Typical applications include securing sheet metal panels, attaching duct flanges, and anchoring light-gauge framing components. The hex washer head style is a standard choice where a large clamping surface and wrench-driven installation are both required. Sold individually, with a minimum order quantity of 100 units per order.

Key Features

• No. 2 drill point for self-drilling entry into light-gauge metal without pre-drilling
• Hex washer head provides a wide bearing surface to resist pull-through
• Hex drive allows high torque input with standard hex bit drivers
• Grade 410 stainless steel construction for corrosion resistance in exposed environments
• 3/4 inch length under head suits thin-material fastening in sheet metal and ductwork

Compatibility

Designed as a standard No. 8 self drilling screw for use in light-gauge sheet metal, HVAC ductwork, roofing panels, and similar thin-material fastening applications where a No. 2 drill point is appropriate.

Installation Notes

Installation is performed with a hex bit driver or nut driver sized to the hex head. Ensure the substrate material thickness is within the rated range for a No. 2 drill point before driving. Follow applicable codes and manufacturer guidelines for fastener spacing and load requirements. Always confirm corrosion compatibility between the fastener material and the substrate prior to installation.
