Value Collection TSI0370200P0-050BX Steel Thumb Screw

Product Description

The VALUE COLLECTION TSI0370200P0-050BX is a 2-inch overall length steel thumb screw with an oval head and 3/8-16 UNC threading. Designed for tool-free or finger-tightened fastening applications, this thumb screw is finished in zinc plating to provide basic corrosion resistance in light-duty service environments. Built to Material Grade 2 standards, it is suited for general mechanical assembly, panel attachment, enclosure access, and similar installations where hand adjustment and frequent removal are required. Electricians, HVAC technicians, and mechanical contractors commonly use oval-head thumb screws when securing access panels, junction box covers, or equipment housings that require regular service access.

This thumb screw is appropriate for use in residential and light commercial mechanical assemblies where a UNC-threaded, hand-adjustable fastener is needed. The oval head profile provides a comfortable grip surface for finger tightening without tools. Its zinc-plated steel construction makes it a practical choice for indoor and protected indoor-outdoor enclosures, control panels, and equipment covers across HVAC, electrical, and general mechanical trades.

Key Features

• 3/8-16 UNC thread standard for broad compatibility with standard tapped holes
• 2-inch overall length suits standard panel and cover fastening applications
• Oval head design allows comfortable finger tightening and tool-free removal
• Zinc-plated finish provides basic corrosion protection for light-duty use
• Steel construction with Material Grade 2 for reliable general-purpose performance
• Without shoulder configuration for straightforward through-hole or tapped-hole installation

Compatibility

Designed as a general-purpose UNC thumb screw compatible with any standard 3/8-16 tapped hole used in mechanical panels, enclosures, and equipment housings across HVAC, electrical, and light mechanical applications.

Installation Notes

Installation does not require specialized tools — hand tightening to snug contact is the intended method for oval-head thumb screws. Ensure the receiving tapped hole is clean and free of debris before threading to avoid cross-threading the zinc-plated steel fastener. Do not use power tools or wrenches to drive this fastener, as over-torquing can strip the threads or damage the head. Always de-energize or shut off equipment before removing or installing access panel fasteners.
