Value Collection -34423-1/2 Oval Head Thumb Screw 25pk

Product Description

The VALUE COLLECTION -34423-1/2 is a Grade 2 steel thumb screw with an oval head and a 1/4-20 UNC thread pattern. It measures 0.5 inches in overall length and carries a zinc-plated finish for basic corrosion resistance. The shoulder-style body provides a positive seating surface when driven into mating hardware. These screws are installed by hand, making them suited for panels, access covers, jigs, and fixtures where tool-free fastening is required. Each package contains 25 pieces, making them practical for stocking in maintenance carts, assembly bins, or service kits across light industrial and mechanical applications.

Thumb screws of this type are commonly used in light-duty clamping, panel retention, and fixture assembly across HVAC equipment enclosures, electrical panel covers, and general mechanical assemblies. The 1/4-20 UNC thread is one of the most widely used coarse-thread standards in inch-measurement hardware, giving this fastener broad utility wherever a hand-tightened connection is needed. The oval head profile seats flush against flat surfaces and provides a comfortable grip surface for repeated hand operation in service and maintenance routines.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard inch-measurement hardware
• Oval head with shoulder for positive seating and hand-tightened installation without tools
• Grade 2 steel construction provides adequate strength for light-duty fastening applications
• Zinc-plated finish offers basic corrosion resistance in indoor environments
• 0.5 inch overall length suits shallow panel and cover retention applications
• Sold in a 25-piece package for efficient stocking and service use

Compatibility

Designed as a standard inch-measurement thumb screw for use in any application requiring a hand-tightened 1/4-20 UNC fastener with an oval head profile.

Installation Notes

These fasteners are installed and removed by hand. Always verify that the mating thread is 1/4-20 UNC before installation to avoid cross-threading. Inspect the zinc-plated finish before use in environments with moisture exposure, as this finish is rated for light-duty indoor corrosion resistance only. No tools are required for standard installation; do not use a driver or wrench, as over-torquing an oval head thumb screw can damage the head or strip the mating thread.
