Value Collection TSI0250050P0-100BX Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION TSI0250050P0-100BX is a Grade 2 steel thumb screw with an oval head and a 1/4-20 UNC thread pattern. At 0.5 inches overall length, this fastener is designed for hand-tightening applications where tools are not practical or available. The zinc-plated finish provides a base level of corrosion resistance for general indoor use. Sold in a box of 100, this SKU suits maintenance, assembly, and light manufacturing environments where consistent fastener supply is needed. Technicians and assemblers working in HVAC panels, electrical enclosures, and equipment access covers commonly use this style of thumb screw.

This thumb screw is suited for applications requiring tool-free fastening and removal. The oval head profile provides a comfortable grip for hand operation. The 1/4-20 UNC thread is one of the most common unified coarse thread standards in inch-based mechanical assembly, making this fastener compatible with a wide range of tapped holes in sheet metal panels, enclosures, and light-duty equipment frames. The box quantity of 100 supports shop stock, field kits, and MRO supply operations where thumb screws are consumed in volume.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• Oval head profile for comfortable hand-tightening without tools
• Grade 2 steel construction for general-purpose mechanical strength
• Zinc-plated finish for basic corrosion resistance in indoor environments

Compatibility

Designed as a general-purpose replacement or stock thumb screw for any application using 1/4-20 UNC tapped holes in panels, enclosures, or light equipment assemblies.

Installation Notes

Thumb screws are installed by hand and do not require tools under normal service conditions. Verify that the mating tapped hole is clean and free of damage before threading. Do not overtighten by hand or with tools, as the fastener is rated for hand-torque application only. For use in electrical enclosures, ensure power is de-energized before accessing the panel.
