Value Collection MSC-74124769 Self Drilling Screw 8

Product Description

The VALUE COLLECTION MSC-74124769 is a Number 8, pan head, self drilling screw designed for metal-to-metal and light sheet metal fastening applications. It features a Phillips drive and a Number 2 drill point that cuts its own pilot hole without pre-drilling. The length under head measures 1/2 inch. Constructed from Grade 410 stainless steel, this screw offers good corrosion resistance along with adequate hardness for drilling into light-gauge metal. It is suitable for use by HVAC technicians, electricians, plumbers, and general sheet metal tradespeople who need a reliable self-tapping fastener with a low-profile pan head seating.

This screw is commonly used in light-gauge sheet metal assembly, HVAC ductwork fabrication, electrical enclosure installation, and similar trade applications where a flush-seating pan head is preferred. The Number 2 drill point is appropriate for sheet metal gauges typically encountered in residential and light commercial mechanical work. The 410 stainless steel construction makes it a better choice than carbon steel in environments with moderate moisture exposure, such as mechanical rooms, rooftop units, and outdoor enclosures.

Key Features

• Number 2 drill point eliminates the need for a pre-drilled pilot hole in light-gauge sheet metal
• Grade 410 stainless steel construction provides corrosion resistance beyond standard carbon steel fasteners
• Pan head profile seats flush and distributes clamping load evenly across the fastened surface
• Phillips drive is compatible with standard power drivers and manual screwdrivers used in the field
• 1/2 inch length under head suits thin sheet metal and light-gauge substrate applications

Compatibility

Designed as a standard Number 8 self drilling screw suitable for light-gauge sheet metal fastening tasks in HVAC, electrical, and plumbing trade applications.

Installation Notes

Install with a Phillips bit driver set to appropriate clutch torque to avoid stripping the pan head drive recess. Ensure the workpiece is secured before driving to prevent walking of the drill point. When installing in stainless steel substrates, use a lower RPM to reduce heat buildup and galling. Follow applicable mechanical and building codes for fastener type and spacing in structural or pressure-bearing assemblies.
