Value Collection TSI0250075P0-100BX Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION TSI0250075P0-100BX is a zinc-plated steel thumb screw with a 1/4-20 UNC thread and an oval head profile. At 3/4 inches overall length and Grade 2 steel construction, this thumb screw is built for light-duty fastening applications where hand-tightening is required and tool access is limited or undesirable. The zinc plating provides basic corrosion resistance for general indoor use. Sold in a box of 100, it suits contractors, tradespeople, and maintenance teams who need a reliable stock of standard thumb screws on hand for panels, enclosures, access doors, and equipment covers.

This thumb screw is suited for residential and light commercial applications where quick, repeated access is needed without tools. Common uses include securing electrical panel covers, HVAC equipment access doors, junction box lids, and similar assemblies. The oval head style provides a low-profile grip surface while the 1/4-20 UNC thread matches the most widely used standard inch-series tapped holes in trade hardware and equipment enclosures.

Key Features

• 1/4-20 UNC thread for compatibility with standard inch-series tapped holes
• Oval head design allows hand-tightening without tools
• Grade 2 steel construction for light-duty fastening strength
• Zinc-plated finish provides basic corrosion resistance
• 3/4 inch overall length suits shallow-thread panel and enclosure applications

Compatibility

Designed as a standard replacement or stock thumb screw for any assembly using 1/4-20 UNC tapped holes requiring a without-shoulder, oval-head style fastener measured in the inch system.

Installation Notes

Install and remove by hand only; do not use a wrench or driver, as over-torquing will damage the knurled head or strip the thread. Verify that the receiving tapped hole is clean and free of debris before threading in. Where thumb screws secure electrical enclosures or panel covers, de-energize the circuit before removing or reinstalling the cover per applicable NEC requirements.
