Value Collection C52000421 Size 14 Truss Head Sheet Metal Screw

Product Description

The VALUE COLLECTION C52000421 is a size 14 truss head sheet metal screw designed for secure fastening in sheet metal and light-gauge metal applications. Manufactured from 18-8 stainless steel, this screw delivers solid corrosion resistance in both indoor and outdoor environments. The Phillips drive allows for fast installation with standard power tools or hand drivers. The 3/4-inch length is measured under the head, making it well suited for thin-gauge assemblies where precise penetration depth matters. Electricians, HVAC technicians, and sheet metal workers regularly use this fastener when assembling ductwork, enclosures, junction boxes, and equipment housings.

This fastener is a standard choice for light-gauge sheet metal work in residential and commercial HVAC installations, electrical panel and enclosure assembly, and general sheet metal fabrication. The truss head profile provides a wide, low-profile bearing surface that spreads clamping load across thin material without pulling through. It is suitable for applications where a flush or low-profile head is preferred over a pan or hex head configuration. Stainless steel construction makes it appropriate for environments with moderate moisture exposure or where galvanic concerns rule out carbon steel fasteners.

Key Features

• Size 14 thread for positive engagement in light-gauge sheet metal
• Truss head provides wide bearing surface and low-profile appearance
• Phillips drive compatible with standard bits and power drivers
• 18-8 stainless steel construction for corrosion resistance
• 3/4-inch length under head for controlled penetration depth
• Inch measurement system for compatibility with standard US trade hardware

Compatibility

Designed as a standard size 14 truss head sheet metal screw for use in light-gauge sheet metal assemblies, HVAC ductwork, electrical enclosures, and general metal fabrication where an 18-8 stainless steel fastener is specified.

Installation Notes

Installation is performed by HVAC technicians, electricians, and sheet metal fabricators using standard Phillips bit drivers or power screwdrivers. Confirm material thickness and gauge compatibility before driving to avoid stripping or deforming thin sheet stock. De-energize all electrical enclosures and follow lockout/tagout procedures before fastening near live components. Do not overtorque stainless steel fasteners, as galling can occur at high drive speeds without appropriate lubrication.
