Value Collection TSI0370300P0-050BX Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION TSI0370300P0-050BX is a steel thumb screw with an oval head profile and a 3/8-16 UNC/UNF thread size. It measures 3 inches overall length and carries a zinc-plated finish for basic corrosion resistance. Material grade 2 steel provides adequate strength for general fastening tasks where hand-tightening is the intended installation method. This fastener is used in light mechanical assemblies, panel access points, enclosures, and equipment covers where tools-free removal is required during routine service or adjustment. Electricians, HVAC technicians, and general mechanical tradespeople commonly encounter this type of fastener in control panels and equipment housings.

This thumb screw is suited for applications requiring frequent hand-tightened fastening and removal without tooling. The oval head design provides a comfortable grip surface for finger operation. The 3/8-16 thread designation covers both UNC and UNF standards as noted in the specifications. Typical install scenarios include equipment enclosures, junction box covers, access panels, and light-duty fixtures in residential and commercial mechanical systems.

Key Features

Compatibility

Designed as a general-purpose replacement or stock thumb screw for equipment enclosures, control panels, and access covers requiring 3/8-16 threaded hand fasteners.

Installation Notes

Installation requires no special tooling as this fastener is intended for hand-tightening only. Ensure the mating thread in the receiving panel or nut is 3/8-16 before installation to avoid cross-threading. Power down or de-energize any electrical enclosure before opening access panels secured by these fasteners. Do not use impact tools or wrenches on thumb screws, as this can damage the head and distort the thread engagement.
