Value Collection TSI0250150S0-100BX Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION TSI0250150S0-100BX is a Grade 2 steel thumb screw with an oval head and shoulder, designed for hand-tightened fastening applications where tools are not required or practical. The 1/4-20 UNC thread pattern and 1.5-inch overall length make it well suited for panel access, enclosure covers, and equipment housings. A zinc-plated finish provides basic corrosion resistance in light-duty environments. This fastener is commonly installed by maintenance technicians, electricians, HVAC service pros, and general trade workers who need repeatable hand-fastened connections on serviceable equipment.

This thumb screw is appropriate for use in residential and light commercial applications where panels, covers, or assemblies require frequent removal and re-installation without tools. The shouldered design provides a positive seating reference against the mating surface. The oval head offers a smooth, low-profile grip profile for repeated hand operation. Typical installation scenarios include electrical enclosures, HVAC equipment access panels, junction box covers, and machine guards.

Compatibility

Installation Notes

Installation requires no special tools — the oval head is designed for hand tightening only. Do not use a wrench or driver on this fastener, as over-torquing can strip the thread or damage the head profile. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before servicing panels or enclosures secured by this fastener.
