Value Collection R63614922 No. 8 Truss Head Sheet Metal Screw

Product Description

The VALUE COLLECTION R63614922 is a No. 8 truss head sheet metal screw designed for secure fastening in thin-gauge metal assemblies. The slotted drive accepts a standard flat-blade screwdriver or bit, making it a practical choice when clearance for a recessed or Phillips driver is limited. Constructed from Grade 18-8 stainless steel, this fastener resists corrosion in humid and outdoor environments. The low-profile truss head distributes clamping load over a wider bearing surface than a pan or hex washer head, reducing the risk of pull-through in lighter-gauge sheet metal. The 0.5-inch length is measured under the head, as is standard for this fastener type.

This screw is suited for HVAC duct fabrication, electrical enclosure assembly, rooftop unit sheet metal work, and general light-gauge metal fastening. Trade professionals use No. 8 sheet metal screws in a wide range of applications including securing junction box covers, attaching duct flanges, fastening conduit straps to sheet metal panels, and assembling equipment housings. The 18-8 stainless steel construction makes this fastener appropriate for installations exposed to moisture, coastal environments, or chemical-wash service areas.

Key Features

• Grade 18-8 stainless steel construction provides corrosion resistance in wet and outdoor service conditions
• Truss head profile offers a wide bearing surface that reduces pull-through risk in thin sheet metal
• Slotted drive is compatible with standard flat-blade screwdrivers and bits
• 0.5-inch length under head suits light-gauge metal fastening with minimal protrusion
• No. 8 thread size is a widely stocked, interchangeable standard in trade and industrial fastener kits

Compatibility

Designed as a standard No. 8 sheet metal screw for use in light-gauge steel, aluminum, and similar thin-metal assemblies common in HVAC, electrical, and plumbing trade work.

Installation Notes

A licensed sheet metal technician or electrician typically installs this fastener using a flat-blade screwdriver or slotted bit driver. Pre-drilling a pilot hole is recommended in harder or thicker gauges of sheet metal to prevent material distortion and reduce drive torque. De-energize any electrical enclosure or equipment panel before fastening to comply with NFPA 70 lockout-tagout requirements. Avoid over-driving, which can strip the slotted head recess or deform the sheet metal substrate.
