Value Collection MP33850 Self Drilling Screw 1/4 in

Product Description

The VALUE COLLECTION MP33850 is a self-drilling screw designed for fast, reliable fastening in metal-to-metal and metal-to-substrate applications. Built from steel with a zinc-plated finish for corrosion resistance, this screw features a 1/4-inch diameter and measures 1.5 inches under the head. The hex washer head provides a broad bearing surface that resists pull-through, while the hex drive ensures positive bit engagement and high torque transfer. The number 3 drill point eliminates the need for a pre-drilled pilot hole, making it a time-saving choice for sheet metal work, HVAC ductwork, and light structural assembly.

This screw is suited for trade professionals working with light-gauge steel and sheet metal assemblies. Common applications include HVAC duct fabrication and installation, electrical enclosure assembly, metal framing, and general mechanical fastening where a self-tapping pilot is required. The zinc-plated finish provides moderate corrosion resistance appropriate for interior installations. The minimum order quantity is 25 pieces per order, with a package quantity of 1.

Key Features

• Number 3 drill point drills its own pilot hole in light-gauge steel without pre-drilling
• Hex washer head delivers a wide bearing surface to resist pull-through
• Hex drive type allows high torque input with standard hex bit drivers
• Steel construction with zinc-plated finish for corrosion resistance in interior applications
• 1/4-inch screw size with 1.5-inch length under head suits a range of sheet metal thicknesses

Compatibility

Designed as a standard self-drilling fastener for light-gauge steel and sheet metal applications, including HVAC ductwork, metal framing, and electrical enclosures. Verify base material gauge compatibility with the number 3 drill point rating before installation.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, electricians, and general mechanical tradespeople using a hex-drive bit and a variable-speed drill or screw gun. No pilot hole is required for compatible light-gauge steel substrates. Ensure the base material gauge falls within the rated capacity of a number 3 drill point before driving. Apply consistent, perpendicular pressure during driving to prevent cam-out or drill point walking.
