Value Collection TSI0310125P0-100BX Steel Thumb Screw

Product Description

The VALUE COLLECTION TSI0310125P0-100BX is a steel thumb screw with an oval head, designed for hand-tightened fastening applications where tools are not required. The fastener measures 1.25 inches overall length and features a 5/16-18 UNC thread form. The zinc-plated finish provides basic corrosion resistance suited for general indoor and light-duty applications. This is a Material Grade 2 steel fastener manufactured to inch measurement standards. It is commonly installed by maintenance technicians, electricians, plumbers, and HVAC service pros who need quick-access fasteners on panels, covers, and enclosures.

This thumb screw is used in residential and commercial settings where frequent panel removal or cover access is needed. The oval head profile allows a comfortable grip for finger-tightening without tools. Applications include equipment enclosures, junction boxes, access panels, and instrument covers. The 5/16-18 UNC thread standard ensures compatibility with standard tapped holes across a wide range of metalwork and fabricated assemblies. No shoulder is present on this fastener, making it a straight-shank design that seats flush against the mating surface.

Installation Notes

Installation is hand-tightening only — no torque tool is required or recommended for thumb screws. Power down or de-energize any equipment before accessing panels secured by these fasteners. Verify that the mating tapped hole is clean and free of debris before threading to avoid cross-threading the zinc-plated finish. Follow applicable NEC or equipment manufacturer guidelines when securing electrical enclosure covers.
