Value Collection C637447 No. 10 Truss Head Phillips Sheet Metal Screw

Product Description

The VALUE COLLECTION C637447 is a No. 10 truss head Phillips sheet metal screw manufactured from Grade 18-8 stainless steel. With a 1.5-inch length under head, this screw is designed for fastening thin-gauge sheet metal in HVAC ductwork, electrical enclosures, metal roofing, and general sheet metal fabrication. The wide, low-profile truss head distributes load across the material surface, reducing the risk of pull-through. Grade 18-8 stainless steel construction provides corrosion resistance in moderate-exposure environments. Each package contains 100 screws, making this a practical quantity for service calls, shop use, and light production work. HVAC technicians, electricians, and sheet metal workers are the primary installers.

This screw is well suited for residential and light commercial applications where a Phillips drive is preferred for speed with standard power tools. Common uses include securing sheet metal panels, joining duct sections, attaching junction box covers, and fastening metal trim. The truss head profile is especially useful where countersinking is not possible and a broad bearing surface is needed. The Grade 18-8 stainless steel composition resists oxidation in damp mechanical spaces and outdoor-exposed installations.

Compatibility

Designed as a general-purpose No. 10 sheet metal screw suitable for thin-gauge ferrous and non-ferrous sheet metal assemblies in HVAC, electrical, and general metal fabrication applications.

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians, electricians, and sheet metal workers using a Phillips bit with a hand or power driver. Pre-drilling a pilot hole is recommended in heavier-gauge stock to prevent material distortion and bit cam-out. Avoid overtorquing, which can strip the thread engagement in thin sheet metal. Follow applicable SMACNA, NEC, or local mechanical code guidelines for fastener placement and spacing in duct and enclosure assemblies.
