Value Collection 1440TSP Thumb Screw 1/4-20 Oval Head Steel

Product Description

The VALUE COLLECTION 1440TSP is a steel thumb screw designed for hand-tightened fastening applications where tools are not required or practical. This fastener features an oval head profile with a shoulder, a 1/4-20 UNC thread standard, and an overall length of 2.5 inches. The head measures 0.48 inches in diameter and 0.57 inches in height, while the shoulder diameter is 0.43 inches. Constructed from Grade 2 steel with an uncoated finish, this thumb screw suits general mechanical assembly, fixture work, and panel retention tasks across manufacturing, maintenance, and light industrial environments.

This thumb screw is suited for applications requiring frequent manual adjustment or removal without tooling. The with-shoulder design provides a defined bearing surface, making it appropriate for assemblies where controlled positioning or panel alignment is needed. Typical installation scenarios include equipment enclosures, jigs, fixtures, machine guards, and adjustable mechanical assemblies. The 1/4-20 UNC thread is one of the most common unified coarse thread standards, making this fastener compatible with a wide range of tapped holes and threaded inserts in that size.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and inserts
• Oval head profile allows comfortable hand tightening without tools
• With-shoulder design provides a bearing surface for controlled panel or fixture alignment
• Grade 2 steel construction offers reliable strength for general fastening duty
• Uncoated finish suits indoor mechanical and assembly environments
• 2.5 inch overall length accommodates moderate stack-up depths

Compatibility

Designed as a standard replacement or stock thumb screw for any assembly using 1/4-20 UNC tapped holes requiring an oval-head with-shoulder fastener in the 2.5 inch length.

Installation Notes

Thumb screws of this type are installed and removed by hand; no torque wrench is required or recommended. Ensure the mating tapped hole or threaded insert matches the 1/4-20 UNC standard before installation. Inspect threads for damage before assembly to avoid cross-threading. This fastener is intended for non-structural, hand-adjustable applications and should not be used as a primary structural connection.
