Value Collection R52001062 Truss Head Machine Screw 1/4-20

Product Description

The VALUE COLLECTION R52001062 is a slotted truss head machine screw intended for general industrial and mechanical assembly applications. Manufactured from steel with a zinc-plated finish, this fastener measures 1/4-20 thread size at 1-1/2 inches in length, measured under the head. The truss head profile provides a wide, low-profile bearing surface that distributes clamping load over a larger area than a standard pan or round head. The slotted drive accepts a standard flat-blade screwdriver. This screw meets ASME B18.6.3 and SAE J82 dimensional and material standards, making it suitable for use wherever a Grade J82 steel fastener is specified.

This fastener is used across a broad range of trade and industrial applications including HVAC equipment panels, electrical enclosures, light mechanical assemblies, and general sheet metal work. The zinc plating provides moderate corrosion resistance appropriate for indoor or protected environments. It is supplied individually but carries a minimum order quantity of 100 pieces, making it practical for service stock, shop inventory, or production-line use.

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 1/4-20 threaded fastener with a truss head and slotted drive, including panel assembly, enclosure hardware, and light structural connections in indoor or protected settings.

Installation Notes

Install using a flat-blade screwdriver sized to the slot width to avoid cam-out and slot damage. De-energize any electrical equipment and follow applicable NEC or equipment manufacturer lockout procedures before fastening within live enclosures. Do not exceed the torque capacity of the slotted drive; truss head screws are not intended for high-torque power-tool installation without a torque-limiting clutch. Inspect threads in the mating material before installation to confirm 1/4-20 compatibility.
