Value Collection TSI0310200S0-100BX Thumb Screw 5/16-18

Product Description

The VALUE COLLECTION TSI0310200S0-100BX is a steel thumb screw with an oval head, designed for hand-tightening applications where tools are not practical or available. It measures 2 inches in overall length and is threaded 5/16-18, conforming to both UNC and UNF thread standards. The zinc-plated finish provides a base level of corrosion resistance for general indoor use. The oval head profile allows for a secure grip during manual adjustment. This fastener is sold individually and is commonly installed by maintenance technicians, millwrights, electricians, and mechanical assemblers in light-duty industrial and commercial settings.

This thumb screw is suited for panel access covers, enclosure doors, jigs, fixtures, and equipment assemblies where frequent removal and reinstallation is required without tools. The 5/16-18 thread size fits a wide range of standard tapped holes in steel, aluminum, and plastic components. It carries a Material Grade 2 designation, making it appropriate for low-to-medium clamping force applications in non-critical structural uses.

Installation Notes

Thumb screws of this type are installed by hand without the use of power tools; do not use a wrench or driver as over-torquing can strip the thread or damage the mating material. Verify the tapped hole thread pitch matches 5/16-18 UNC or UNF before installation. Inspect threads for damage or debris before seating. This fastener is not rated for structural or high-vibration applications without supplemental locking provisions.
