Value Collection 407-1603 Fully Threaded Stud 4-40 1/2 in

Product Description

The VALUE COLLECTION 407-1603 is a fully threaded stud with a 4-40 UNC thread form and an overall length of 0.5 inches. The stud is fully threaded from end to end, meaning the thread length equals the overall length at 0.5 inches. Manufactured from Grade 5.8 carbon steel with an uncoated plain finish, this stud delivers a minimum tensile strength of 60,000 psi. It is a standard fastener used across light-duty mechanical assemblies, electrical enclosures, and instrumentation panels. Machinists, electricians, and mechanical assembly technicians install this type of hardware during equipment builds, panel fabrication, and component mounting tasks.

This fully threaded stud is suited for applications requiring a small-diameter, fine-thread fastener in tight clearance environments. The 4-40 thread size is commonly found in electronic enclosures, control panel assemblies, HVAC equipment sub-assemblies, and light instrumentation mounting. The uncoated carbon steel construction makes it appropriate for indoor, dry-environment applications where corrosion exposure is minimal. Sold individually per package with a minimum order quantity of 25 pieces.

Key Features

• Fully threaded along entire 0.5 inch length — no unthreaded shank
• 4-40 UNC thread size for fine-pitch, small-diameter fastening
• Grade 5.8 carbon steel with minimum tensile strength of 60,000 psi
• Uncoated plain finish suitable for dry indoor environments
• No flats — round body designed for standard stud installation
• UNSPSC Code 31161618 for procurement and catalog classification

Compatibility

Designed as a standard 4-40 fully threaded stud for use in light mechanical assemblies, electronic enclosures, and control panel fabrication where a 4-40 thread pattern and 0.5 inch length are specified.

Installation Notes

This stud is typically installed by machinists or mechanical assembly technicians using a stud driver or locking-nut method to seat the fastener into a tapped hole. Ensure the mating tapped hole is clean and free of debris before installation. Do not overtighten, as small-diameter 4-40 fasteners are susceptible to thread stripping at excessive torque. Power down any electrical equipment before performing fastener installation or removal in panel or enclosure environments.
