Electro Hardware THS1141M04F16 Aluminum Thumb Screw 1/4-20

Product Description

The ELECTRO HARDWARE THS1141M04F16 is an aluminum thumb screw with a knurled head and a shouldered shank, designed for hand-tightened fastening applications in equipment panels, enclosures, and assemblies. The 1/4-20 UNC thread makes it compatible with standard tapped holes across a wide range of industrial and trade hardware setups. The knurled head provides grip for tool-free installation and removal. The screw measures 1.125 inches in overall length with a 0.5-inch head diameter and a 0.25-inch head height. The brass head material contrasts with the aluminum shank, and the uncoated finish leaves the base material exposed. Licensed tradespeople and maintenance technicians working on panel access points and enclosure covers are the primary installers.

This thumb screw is suited for light-duty fastening in equipment panels, control enclosures, access covers, and similar assemblies where frequent removal is needed without tools. The with-shoulder design adds a bearing surface that helps align and seat mating panels cleanly. Thread size 1/4-20 UNC is a widely used standard pitch, making this screw a fit for both OEM equipment assembly and field maintenance applications across HVAC, electrical, and general industrial trades.

Key Features

• Knurled head for secure finger grip and tool-free removal
• With-shoulder design provides a seating surface for panel alignment
• 1/4-20 UNC thread mates with standard tapped hardware
• Aluminum construction keeps weight low in panel and enclosure assemblies
• Brass head material adds wear resistance at the contact surface
• Uncoated finish — no plating to flake or corrode in dry indoor environments

Compatibility

Designed as a standard 1/4-20 UNC thumb screw for use in equipment panels, enclosures, and access cover assemblies requiring hand-operated fastening.

Installation Notes

Installation does not require power-down procedures for the screw itself, but always follow lockout/tagout protocols before opening any live electrical enclosure or control panel. Hand-tighten only — the knurled head is not designed for wrench torque. Ensure the mating tapped hole is clean and the thread is free of debris before installation. Follow applicable NEC or equipment manufacturer guidelines when accessing enclosures.
