Value Collection A997259 Machine Screw 1/4-20 Truss Head 50pk

Product Description

The VALUE COLLECTION A997259 is a 1/4-20 x 1-1/2-inch truss head machine screw designed for general mechanical fastening in trade and industrial applications. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw delivers solid corrosion resistance in both indoor and outdoor environments. The truss head profile provides a wide, low-profile bearing surface, and the Phillips drive allows for fast installation with standard power or hand tools. Thread size follows the UNC standard. Length measurement is taken under the head. Sold in a package of 50 pieces.

This fastener is suited for HVAC panel assembly, electrical enclosure work, plumbing equipment mounting, and general equipment fabrication where corrosion resistance and a clean bearing surface are required. The 1/4-20 UNC thread is one of the most common coarse-thread sizes in trade work, making this screw a practical stock item for service vans and shop inventory. The stainless steel construction makes it appropriate for humid or washdown-adjacent environments where carbon steel would corrode prematurely.

Compatibility

Designed as a standard 1/4-20 UNC coarse-thread machine screw suitable for use wherever a truss head Phillips fastener of this thread size and length is specified.

Installation Notes

Install using a Phillips No. 2 bit or matching hand screwdriver. De-energize electrical equipment and shut off system power before fastening or removing screws in any live panel or enclosure. Apply fastener torque consistent with the equipment manufacturer's specifications for 1/4-20 hardware. Avoid mixing stainless steel fasteners with dissimilar metals in highly conductive or galvanic environments without appropriate isolation.
