Value Collection R63280161 Thumb Screw 1/4-20 Oval Head

Product Description

The VALUE COLLECTION R63280161 is an 18-8 stainless steel thumb screw designed for hand-tightened fastening applications where tools are not required. It features a 1/4-20 UNC thread and an oval head profile with a shouldered shank, giving it positive seating and a clean look on finished surfaces. The 18-8 stainless steel construction provides corrosion resistance suited for both indoor and light outdoor environments. With a head diameter of 0.55 inches and a head height of 0.64 inches, this thumb screw suits installations requiring a low-profile yet grippable fastener. Overall length is 3/4 inch. Installers in HVAC, electrical, and light mechanical trades use thumb screws like this for access panels, enclosures, and equipment covers.

This thumb screw is appropriate for general trade and industrial fastening tasks where frequent hand removal and reinstallation is needed. Typical applications include securing access panels on HVAC equipment, junction box covers, control enclosures, and similar assemblies. The 1/4-20 UNC thread is a common inch-standard size compatible with a wide range of tapped holes and threaded inserts found in residential and light commercial equipment. The with-shoulder design helps locate the screw in clearance holes and prevents the fastener from pulling through thin material.

Installation Notes

Installation requires no tools under normal hand-tightening use. Ensure the mating tapped hole or threaded insert is clean and free of debris before driving the screw. Do not use power tools to drive thumb screws, as over-torquing will damage the knurled head or strip the thread. When used on electrical enclosures, follow applicable NEC guidelines for panel access and grounding continuity.
