Value Collection -34442-1/2 Thumb Screw 1/4-20 Zinc-plated 25pk

Product Description

The VALUE COLLECTION -34442-1/2 is an oval head thumb screw designed for hand-tightened fastening applications where tools are not required or practical. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener resists corrosion in typical indoor environments. The 1/4-20 UNC thread pattern is one of the most common inch-series coarse threads in use across industrial, HVAC panel, electrical enclosure, and general mechanical assembly work. At 0.5 inches overall length, this screw is suited for thin-panel or light-duty clamping tasks. Each package contains 25 pieces, making it practical for stocking service vans or shop bins.

This thumb screw is used wherever quick, repeated access is needed without tools — access panels, junction box covers, equipment guards, filter frames, and light-duty fixtures. The oval head profile provides a low-profile grip surface that seats flush or near-flush against the mating surface. It is a standard inch-series fastener appropriate for residential and light commercial equipment assemblies. Trade professionals in HVAC, electrical, and plumbing service commonly stock this size for field repairs and panel work.

Key Features

• 0.5 inch overall length suits thin-panel and shallow-depth installations
• Pack of 25 supports stocking and multi-point installations

Compatibility

Designed as a standard 1/4-20 UNC inch-series oval head thumb screw suitable for general mechanical assemblies, access panels, and equipment enclosures requiring tool-free fastener access.

Installation Notes

Installation requires no tools under normal hand-tightening conditions. Confirm the mating threaded hole or nut is clean and free of debris before threading to avoid cross-threading. Do not exceed hand-tight torque, as Grade 2 steel thumb screws are not rated for high-clamp-load applications. Follow applicable equipment manufacturer guidelines when used on electrical enclosures or HVAC panels.
