Value Collection MP33829-4 No. 8 Self Drilling Screw

Product Description

The VALUE COLLECTION MP33829-4 is a No. 8 self-drilling screw designed for fast, reliable fastening in steel and light metal applications without a pre-drilled pilot hole. It features a hex washer head with a hex drive, providing high torque transfer and a built-in washer-style bearing surface that resists pull-through. The screw measures 1 inch in length under the head and is fitted with a No. 2 drill point for clean entry into sheet metal, light-gauge steel, and similar substrates. Constructed from steel with a zinc-plated finish, it offers basic corrosion resistance for general indoor and light-duty applications. Sold in multiples of 50.

This screw is suited for sheet metal assembly, HVAC duct fabrication, electrical enclosures, metal framing, and similar trade applications where a self-tapping, self-drilling fastener is required. The hex washer head seats flush against the workpiece surface, making it a common choice for securing ductwork panels, junction box covers, and light structural sheet metal connections in both residential and commercial settings.

Key Features

• No. 2 drill point drills its own pilot hole, eliminating a separate drilling step
• Hex washer head provides a wide bearing surface to resist pull-through
• Hex drive compatible with standard hex-drive bits and nut drivers
• Steel construction with zinc-plated finish for basic corrosion resistance
• 1 inch length under head suits standard sheet metal and light-gauge applications
• Minimum order quantity of 50 pieces supports job-site and shop use

Compatibility

Designed as a general-purpose No. 8 self-drilling screw suitable for light-gauge sheet metal, HVAC ductwork, electrical enclosures, and similar metal fastening applications where a No. 2 drill point is appropriate.

Installation Notes

Installation is performed with a hex-drive bit or nut driver in a standard drill or impact driver set to a controlled torque to avoid stripping the head or over-driving through thin material. Power down or de-energize any electrical enclosure or HVAC system before fastening panels or covers. Do not use self-drilling screws on materials exceeding the rated penetration capacity of the No. 2 drill point, as forcing the screw can result in bit cam-out or fastener failure.
