Value Collection C637431 No. 8 Truss Head Phillips Sheet Metal Screw

Product Description

The VALUE COLLECTION C637431 is a No. 8 truss head sheet metal screw with a Phillips drive, designed for fastening thin-gauge metal panels, ductwork, electrical enclosures, and light structural sheet metal assemblies. The screw measures 1 inch in length under the head and is manufactured from 18-8 stainless steel, offering solid corrosion resistance in humid or outdoor-exposed installations. The low-profile truss head provides a wide bearing surface that resists pull-through on thin sheet stock. HVAC technicians, electricians, and plumbers routinely use this screw type when securing sheet metal components where a flush-style or pan head would not seat properly. Sold in a 100-piece pack.

This screw is suited for light-gauge sheet metal work encountered in residential and commercial HVAC ductwork fabrication, electrical panel trim, junction box covers, and general mechanical room work. The Phillips drive is compatible with standard No. 2 Phillips bits used across all trades. The 18-8 stainless steel construction makes it appropriate for installations in mechanical spaces where moisture, condensation, or mild chemical exposure is a factor.

Key Features

• No. 8 thread size for reliable bite in light-gauge sheet metal
• 1 inch length under head accommodates standard sheet metal thicknesses
• Truss head profile delivers wide bearing surface to minimize pull-through
• Phillips drive works with standard No. 2 Phillips bits and power drivers
• 18-8 stainless steel construction resists corrosion in humid or wet mechanical environments
• 100-piece pack quantity reduces per-job procurement trips

Compatibility

Designed as a general-purpose sheet metal fastener suitable for light-gauge ferrous and non-ferrous sheet metal applications across HVAC, electrical, and plumbing trades.

Installation Notes

Installation is performed with a No. 2 Phillips bit in a hand driver or variable-speed power drill set to a low clutch setting to avoid stripping the drive or over-driving the screw. Pre-drilling a pilot hole is recommended when fastening into heavier gauge stock to prevent sheet distortion. Follow applicable mechanical and electrical codes, such as NEC guidelines for enclosure fasteners, when using in code-governed assemblies. Wear appropriate eye protection when driving screws into sheet metal edges.
