Value Collection TSI0370075P0-050BX Thumb Screw 3/8-16

Product Description

The VALUE COLLECTION TSI0370075P0-050BX is a steel thumb screw with an oval head profile, designed for hand-tightened fastening applications where tools are not required or practical. The screw features a 3/8-16 UNC thread pattern and measures 3/4 inches in overall length. It carries a zinc-plated finish that provides a basic level of corrosion resistance for general-duty use. Grade 2 steel construction delivers adequate tensile strength for light-to-medium clamping and adjustment tasks. This fastener is installed by hand and is commonly used in enclosures, panel assemblies, jigs, fixtures, and equipment covers across HVAC, electrical, and light industrial applications.

This thumb screw suits residential and light commercial installations where frequent manual access is needed without tooling. Typical applications include equipment access panels, control enclosures, junction boxes, and adjustable mounting brackets. The oval head profile provides a low-profile grip surface that seats flush or slightly proud of the mating surface, making it a practical choice for panel retention and field-serviceable assemblies. Licensed tradespeople in HVAC, electrical, and plumbing disciplines regularly stock this fastener size for panel work and equipment maintenance.

Key Features

• 3/8-16 UNC thread for broad compatibility with standard tapped holes and threaded inserts
• Oval head profile allows hand-tightening without a driver in accessible installations
• Zinc-plated finish provides basic corrosion resistance for indoor and sheltered applications
• Grade 2 steel construction suitable for light-to-medium clamping loads
• 3/4 inch overall length fits shallow panel and enclosure wall thicknesses
• No-shoulder design for straightforward through-hole installation

Compatibility

Designed as a standard UNC thumb screw for use in any application requiring a 3/8-16 tapped hole or threaded insert with a 3/4 inch grip range.

Installation Notes

Installation requires no special tooling — the oval head is designed for hand tightening only. Verify that the mating thread is clean and free of debris before engagement to avoid cross-threading. Always de-energize electrical enclosures and follow applicable NEC lockout/tagout procedures before servicing panel fasteners. Do not use an impact driver or wrench on thumb screws, as this can strip the head or over-stress the thread.
