Value Collection A996517 Truss Head Machine Screw 1/4-20

Product Description

The VALUE COLLECTION A996517 is a 1/4-20 x 1-1/4 inch truss head machine screw with a Phillips drive, manufactured from Grade 2 steel with a zinc-plated finish. The truss head profile features a wide, low-profile dome that distributes clamping load over a broader surface area than a standard pan head, making it well suited for thin materials and sheet metal assemblies. The zinc coating provides basic corrosion resistance for general indoor and light-duty applications. These screws follow Unified National Coarse (UNC) thread standards and are sold in a pack of 50. Length is measured under the head at 1-1/4 inches.

These machine screws are used across a wide range of trade applications including HVAC equipment assembly, electrical enclosure mounting, light mechanical fixtures, and general sheet metal work. The truss head and Phillips drive combination is common in production and service environments where standard hand tools or power drivers are in use. Suitable for residential and light commercial applications where Grade 2 steel fasteners meet the structural requirements.

Compatibility

Designed as a standard UNC machine screw for use with 1/4-20 tapped holes, threaded inserts, and standard hex or machine screw nuts in general mechanical and trade assemblies.

Installation Notes

Installation does not require specialized trade licensing but should follow applicable mechanical or electrical codes when used in code-governed assemblies. Ensure mating threads are clean and free of debris before driving. Do not overtorque Phillips-drive fasteners, as cam-out can damage the drive recess. Use the correct Phillips bit size to maintain drive engagement and avoid stripping.
