Value Collection D30012 Hex Head Cap Screw 1/4-20 X 3 in

Product Description

The VALUE COLLECTION D30012 is a 1/4-20 hex head cap screw designed for general mechanical assembly and structural fastening applications. With a 3-inch length under head and partial threading, this fastener provides a bearing surface against unthreaded material, making it suitable for clamping applications where a smooth shank is required through one or more layers. Manufactured from Grade 5 steel with a zinc-plated finish, it meets ASME B18.2.1 dimensional standards. The zinc coating provides a base level of corrosion resistance for indoor and light-duty outdoor environments. Installed using a standard hex wrench or socket, this screw suits maintenance, fabrication, and equipment assembly work.

This fastener is appropriate for use in residential and commercial mechanical equipment installation, HVAC equipment mounting, electrical enclosure assembly, and general trade service work where 1/4-20 UNC thread fasteners are specified. The 3-inch length makes it suited for applications requiring reach through thicker material stacks or brackets. Trade professionals in HVAC, plumbing, and electrical disciplines commonly use this thread size and length combination for panel and bracket attachment.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-system tapped holes
• 3-inch length under head with partial threading, providing a smooth shank section for clamping applications
• Grade 5 steel construction for improved tensile strength over Grade 2 fasteners
• Zinc-plated finish for baseline corrosion resistance in light-duty environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment

Compatibility

Designed as an OEM-style replacement or service fastener for any application specifying a 1/4-20 UNC hex head cap screw with a 3-inch length under head.

Installation Notes

Installation requires a standard 7/16-inch hex wrench or socket. Always verify thread engagement depth and torque to the equipment manufacturer specification for 1/4-20 Grade 5 fasteners. For installations governed by NEC or mechanical codes, confirm fastener grade requirements in the applicable equipment documentation before substituting hardware. Do not overtighten into aluminum or light-gauge steel tapped holes.
