Value Collection TSI0310100P0-100BX Steel Thumb Screw

Product Description

The VALUE COLLECTION TSI0310100P0-100BX is a Grade 2 steel thumb screw with an oval head and a zinc-plated finish. It is designed for hand-tightened fastening applications where tools are not required or practical. The 5/16-18 UNC thread provides a coarse-pitch engagement suitable for metal, wood, and panel assemblies. At 1 inch overall length and without a shoulder, this thumb screw suits shallow through-hole and threaded insert applications. The zinc plating provides basic corrosion resistance for dry indoor environments. Electricians, HVAC technicians, panel assemblers, and general trade professionals use this style of fastener for access panels, equipment covers, and component mounting.

This thumb screw is well suited for light-duty fastening tasks in residential and commercial service environments. Typical applications include securing electrical enclosure covers, HVAC service panels, junction box lids, and other removable components that require frequent access. The oval head profile sits low against the mating surface and offers a comfortable grip for repeated hand operation. It is sold individually, with a minimum order quantity of 10 pieces.

Compatibility

Installation Notes

Installation requires no special tools; the oval head is intended for hand tightening only. Always de-energize electrical equipment or shut off relevant systems before removing or replacing panel fasteners. Do not use impact drivers or wrenches on thumb screws, as this can strip the head or damage the mating thread. Follow applicable NEC or equipment manufacturer guidelines when servicing enclosed electrical or HVAC assemblies.
