Value Collection R63283969 Brass Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION R63283969 is a brass thumb screw with a 1/4-20 UNC thread and an oval head profile. Designed for hand-tightening applications, this fastener allows tool-free assembly and disassembly in panels, enclosures, fixtures, and light-duty mechanical assemblies. The oval head provides a smooth, ergonomic gripping surface for repeated adjustment. With a head diameter of 0.55 inches and a head height of 0.64 inches, the fastener is compact enough for confined spaces while still offering adequate torque by hand. Overall length is 0.75 inches. Brass construction offers natural corrosion resistance and electrical non-conductivity, making this screw suitable for both general mechanical and electrical enclosure applications.

This thumb screw is commonly used in residential and light commercial settings where access panels, junction boxes, equipment covers, or instrument housings require periodic removal without tools. Trade professionals in HVAC, electrical, and plumbing service work frequently use thumb screws on access doors, filter frames, and control panels where repeated service access is required. The 1/4-20 UNC thread is a widely standardized size, making this screw a practical stock item for field service kits and shop inventory.

Installation Notes

Installation is performed by hand without tools under normal service conditions. De-energize any electrical enclosure or panel before accessing interior components when replacing or installing thumb screws in those assemblies. Ensure the mating threaded hole or nut is clean and free of debris before threading in the fastener. Do not over-tighten by hand, as brass threads can be damaged by excessive force.
