Value Collection R52001033 Machine Screw 1/4-20x1/2 Hex Washer

Product Description

The VALUE COLLECTION R52001033 is a 1/4-20 x 1/2 inch machine screw with a hex washer head and slotted drive. It is manufactured from steel with a zinc-plated finish for corrosion resistance in general-purpose fastening applications. The screw meets ASME B18.6.3 and SAE J82 standards, confirming dimensional accuracy and material consistency. Overall length is 1/2 inch, measured from the underside of the head to the tip. This fastener is used by electricians, HVAC technicians, plumbers, and general trade professionals wherever a 1/4-20 thread pattern and a low-profile hex washer head are required.

This screw is suited for light-duty mechanical assemblies, electrical enclosures, HVAC equipment panels, and similar trade applications where a slotted hex washer head provides both wrench and screwdriver access. The zinc plating offers adequate protection in dry or mildly humid indoor environments. Sold in multiples of 100 units per order.

Installation Notes

Installation requires a flat-blade screwdriver or appropriately sized wrench for the hex washer head. Ensure the receiving thread is clean and free of debris before driving the fastener. Do not overtighten, as doing so can strip the slotted drive or damage the mating thread. Follow applicable mechanical and electrical codes for the specific assembly being serviced.
