Value Collection D30014 Hex Head Cap Screw 1/4-20 X 3.5 in

Product Description

The VALUE COLLECTION D30014 is a 1/4-20 UNC hex head cap screw designed for general mechanical assembly across industrial, commercial, and trade applications. The screw measures 3-1/2 inches under the head and features partial threading along its shank. Manufactured from Grade 5 steel with a zinc-plated finish, it delivers reliable tensile strength and basic corrosion resistance suitable for indoor and light-duty outdoor fastening. It conforms to ASME B18.2.1 standards, making it a consistent, spec-compliant choice for professional installers and maintenance technicians working with inch-series fasteners.

This hex head cap screw is used in a wide range of trade and mechanical applications including HVAC equipment mounting, electrical enclosure assembly, plumbing support hardware, and general structural fastening. The 1/4-20 UNC thread pattern is one of the most common inch-series thread standards, making this screw compatible with a broad range of tapped holes, nuts, and threaded inserts found throughout residential and commercial equipment installations.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series hardware
• 3-1/2 inches length under head for use in deeper through-hole or stacked-material applications
• Grade 5 steel construction for improved tensile and proof load strength over Grade 2
• Zinc-plated finish provides basic corrosion resistance and surface protection
• Partial threading allows clamping force across unthreaded shank sections
• Meets ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed for use with standard 1/4-20 UNC tapped holes, hex nuts, and threaded inserts conforming to inch-series dimensional standards across general mechanical and trade assembly applications.

Installation Notes

Installation is performed with a standard hex wrench or socket driver sized for a 1/4-20 hex head fastener. Ensure mating threads are clean and free of debris before driving. Do not overtighten into tapped aluminum or plastic housings. Follow applicable equipment manufacturer torque specifications and relevant codes when fastening structural or load-bearing assemblies.
