Value Collection TSI0250150P0-100BX Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION TSI0250150P0-100BX is a Grade 2 steel thumb screw with a 1/4-20 UNC thread and an oval head profile. At 1.5 inches overall length, it delivers a secure, hand-tightened fastening solution without the need for a driver. The zinc-plated finish provides a basic layer of corrosion resistance for general indoor applications. Sold in a box of 100, this screw is a practical choice for maintenance shops, panel fabricators, electricians, and HVAC technicians who need reliable manual-release fasteners in volume.

This thumb screw is suited for light-duty panel access covers, electrical enclosures, equipment housings, and other assemblies where frequent hand-tightening and removal is required. The oval head provides a comfortable grip surface for repeated field adjustments. Without a shoulder, the shank threads fully along the fastened length, making it appropriate for through-hole and tapped applications where the full 1/4-20 thread engagement is needed.

Compatibility

Designed as a standard 1/4-20 UNC thumb screw for use in tapped holes or with matching 1/4-20 threaded hardware in enclosures, panels, and equipment access covers requiring tool-free fastening.

Installation Notes

De-energize all electrical equipment and follow applicable NEC guidelines before accessing panels or enclosures where these screws are installed. Verify the receiving thread is 1/4-20 UNC and that the panel material thickness is compatible with the 1.5-inch overall length. Hand-tighten only - do not use a driver or wrench on thumb screws, as this can strip threads or damage the head. Inspect threads for cross-threading before full engagement.
