Value Collection 403034PR Hex Head Cap Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION 403034PR is a 1/4-20 hex head cap screw designed for general-purpose fastening applications across mechanical, HVAC, plumbing, and electrical assembly work. This fastener measures 3 inches in length under the head and features partial threading along the shank, which helps align mating components and reduces the risk of cross-threading in through-hole applications. The screw is manufactured from Grade 2 steel with a zinc-plated finish that provides baseline corrosion resistance for indoor and light-duty outdoor environments. Drive engagement is achieved with a 7/16-inch hex key or wrench. Licensed tradespeople and assembly technicians working with standard inch-series hardware will find this a straightforward UNC-thread replacement or new-installation fastener.

This screw is suited for light to medium-duty structural and mechanical assembly where 1/4-20 UNC thread is specified. Common applications include equipment panel mounting, bracket attachment, and component assembly in residential and light commercial systems. The partial-thread design makes it particularly useful when clamping two components together with a nut, as the unthreaded shank bears the shear load. This fastener ships in single units with a minimum order quantity of 100 pieces, making it appropriate for stocking or job-lot purchasing by trade shops and service vehicles.

Key Features

• 1/4-20 UNC thread standard for broad compatibility with inch-series hardware
• 3-inch length under head, partially threaded for shear-load-bearing applications
• Grade 2 steel construction provides adequate tensile strength for light to medium-duty use
• Zinc-plated finish offers corrosion resistance in dry and low-moisture environments
• 7/16-inch hex drive fits standard wrenches and sockets common on most tool sets
• Minimum order quantity of 100 pieces supports bulk stocking for service operations

Compatibility

Designed as a standard inch-series UNC fastener compatible with any tapped hole or nut rated for 1/4-20 thread. No specific OEM compatibility is stated for this part.

Installation Notes

Installation requires a 7/16-inch wrench or socket. Always ensure the mating thread or nut is clean and free of debris before driving the fastener. Do not exceed the torque rating of Grade 2 hardware; consult applicable fastener standards or equipment manufacturer documentation for torque specifications. Disconnect power or shut off relevant systems before working in panels or enclosures where this fastener is being installed or replaced.
