Value Collection D30160-21/4 Hex Cap Screw 3/4-10 X 2-1/4 in Grade 5

Product Description

The VALUE COLLECTION D30160-21/4 is a fully threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and equipment assembly applications. It carries a 3/4-10 UNC thread size with a 2-1/4 inch length under the head. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener meets ASME B18.2.1 dimensional standards. Grade 5 steel provides a meaningful step up in tensile strength over Grade 2, making it a reliable choice where moderate-to-high clamping force is required. The zinc plating offers basic corrosion resistance suitable for indoor and sheltered outdoor environments.

This fastener is commonly used in light industrial machinery, HVAC equipment frames, structural brackets, and general fabrication work. It is appropriate for residential and commercial service applications where a standard inch-series coarse-thread hex cap screw is specified. Tradespeople across HVAC, plumbing, and electrical disciplines reach for Grade 5 fasteners when OEM replacement or field fabrication calls for a reliable, code-recognized standard fastener. Minimum order quantity is 10 pieces.

Key Features

• 3/4-10 UNC coarse thread for broad compatibility with standard tapped holes and nuts
• Fully threaded along the 2-1/4 inch under-head length for maximum thread engagement
• Grade 5 steel construction for improved tensile and proof load strength over Grade 2
• Zinc-plated finish provides basic corrosion and oxidation resistance
• Conforms to ASME B18.2.1 dimensional standard for consistent fit and interchangeability

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use with any 3/4-10 UNC tapped hole, nut, or threaded insert in equipment, structural, or fabrication applications.

Installation Notes

Installation is performed with a standard 1-1/8 inch hex wrench or socket driver appropriate for a 3/4-10 fastener. Always verify that the mating thread is clean and undamaged before installation. Do not exceed the torque ratings specified by the equipment manufacturer or applicable structural standards. When used in electrical or HVAC panel enclosures, confirm that fastener length does not intrude into live-voltage areas.
