Value Collection TSI0370100S0-100BX 3/8-16 Thumb Screw

Product Description

The VALUE COLLECTION TSI0370100S0-100BX is a Grade 2 steel thumb screw with a 3/8-16 UNC thread and an oval head profile. It measures 1 inch overall length and carries a zinc-plated finish for basic corrosion resistance in dry to mildly humid environments. The shoulder-type design provides a stable seating surface, making it suitable for hand-tightened fastening applications where tools are not required or practical. Electricians, HVAC installers, panel fabricators, and general maintenance trades use oval-head thumb screws when frequent access or adjustment is part of normal workflow.

This thumb screw is suited for light-duty fastening in control panels, electrical enclosures, equipment covers, jigs, and fixtures where finger-tightening is preferred. The 3/8-16 UNC thread is a common imperial thread standard, compatible with standard 3/8-16 tapped holes and threaded inserts found across a wide range of commercial and industrial equipment. The zinc plating provides a clean appearance and modest surface protection in indoor applications.

Key Features

• 3/8-16 UNC thread for compatibility with standard imperial tapped holes
• Oval head profile for comfortable finger-tightening without tools
• With-shoulder design provides a positive seating surface
• 1 inch overall length suits shallow-depth fastening applications
• Zinc-plated finish offers basic corrosion resistance for indoor use
• Grade 2 steel construction balances strength and cost for general-purpose use

Compatibility

Designed for use in any application with a standard 3/8-16 UNC tapped hole or threaded insert requiring hand-tightened, tool-free fastening.

Installation Notes

Hand-tighten only — thumb screws are not rated for torque-wrench installation and over-tightening can strip the thread or damage the head. Confirm the receiving thread is clean and free of debris before installation. This fastener is intended for indoor or protected environments; the zinc-plated finish is not suitable for outdoor or high-humidity exposure without additional protective measures.
