Value Collection TSI0370150P0-050BX Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION TSI0370150P0-050BX is a Grade 2 steel thumb screw with a 3/8-16 UNC thread and an oval head profile. At 1.5 inches overall length, this fastener is suited for hand-tightened applications where tools are not practical or permitted. The zinc-plated finish provides basic corrosion resistance for general indoor or light-duty environments. It ships without a shoulder, making it appropriate for through-hole or standard threaded insert applications. Installers in electrical, HVAC, panel assembly, and light mechanical trades commonly use oval-head thumb screws for access panels, enclosure covers, and equipment doors.

This thumb screw is appropriate for residential and commercial applications requiring frequent hand-removal of covers, guards, or access panels. The 3/8-16 UNC thread is a standard coarse-pitch size widely used in steel and aluminum assemblies. The oval head provides a low-profile, rounded grip surface that is easy to turn by hand without tools. This item is sold in a minimum order quantity of 50 pieces, making it well suited for contractors and technicians who stock fasteners in bulk for service vans or shop inventory.

Installation Notes

Thumb screws are installed and removed by hand and do not require a driver or wrench under normal use. Ensure the mating thread in the receiving component is clean and free of debris before installation. Do not over-torque by using tools, as this can damage the oval head or strip the mating thread. For outdoor or high-humidity installations, evaluate whether the zinc-plated finish provides sufficient corrosion protection for the application.
