Value Collection TS-1420-750-NT Steel Thumb Screw 1/4-20

Product Description

The VALUE COLLECTION TS-1420-750-NT is a steel thumb screw with a 1/4-20 UNC/UNF thread and an oval head profile. It is designed for hand-tightening applications where tools are not required or practical. The screw features a dog point tip made of nylon, which provides a non-marring contact surface on the mating part. The body is steel with a zinc-plated finish for basic corrosion resistance. With a length under head of 0.75 inches, a head diameter of 0.81 inches, and a head height of 0.55 inches, this fastener is suited for panel mounting, fixture alignment, and light clamping tasks in mechanical and electrical assemblies.

This thumb screw is used in applications where frequent manual adjustment or removal is needed without tooling. Typical installations include equipment panels, enclosures, jigs, fixtures, and control housings in light mechanical, HVAC, and electrical service work. The nylon dog point tip protects threaded inserts and delicate mating surfaces from galling or scoring during tightening. The zinc-plated steel construction makes it appropriate for indoor or protected indoor-outdoor environments where mild corrosion resistance is acceptable.

Key Features

• 1/4-20 UNC/UNF thread standard for broad hardware compatibility
• Oval head profile with 0.81-inch head diameter for positive finger grip
• Dog point nylon tip measures 1/8 inch diameter and 1/16 inch length, protecting mating surfaces
• Zinc-plated steel finish provides basic corrosion resistance for indoor applications
• 0.75-inch length under head suits shallow panel and fixture mounting needs
• Material Grade 2 steel construction for standard-duty hand-fastening use

Compatibility

Designed as a standard 1/4-20 UNC/UNF thumb screw replacement or addition for equipment panels, enclosures, and fixtures requiring hand-adjustment fasteners with a non-marring nylon dog point tip.

Installation Notes

This thumb screw is installed by hand and does not require a driver or wrench under normal service conditions. Ensure the mating threaded hole is clean and free of debris before installation to avoid cross-threading. Do not over-torque by applying tools to the head, as the nylon dog point tip and Grade 2 steel body are rated for hand-tightening loads only. Follow applicable equipment manufacturer guidelines when securing panels or covers on electrical or HVAC enclosures.
