Value Collection 451050BR Hex Cap Screw 1/4-20 X 7 in Grade 8

Product Description

The VALUE COLLECTION 451050BR is a 1/4-20 UNC hex head cap screw designed for high-strength fastening applications across mechanical, structural, and trade assembly work. Manufactured from Grade 8 steel with a bright uncoated finish, this fastener delivers the tensile strength required for demanding bolted connections. The partially threaded shank measures 7 inches under the head, providing a long grip length suited for through-bolting thick assemblies or stacking multiple components. It meets ASME B18.2.1 dimensional standards, making it a reliable choice for applications where fastener geometry and strength class must conform to recognized specifications. Installation requires a 7/16-inch hex wrench or socket.

This cap screw is suited for general mechanical assembly, equipment mounting, structural connections, and maintenance repair work in industrial, commercial, and trade settings. The Grade 8 classification indicates a minimum tensile strength significantly higher than standard hardware-grade fasteners, making it appropriate for high-load bolted joints in HVAC equipment frames, machinery, and heavy-duty fixtures. The partially threaded design helps prevent thread galling in the grip zone and allows for more precise clamping force on assembled parts. Sold individually with a minimum order of 10 pieces.

Key Features

• 1/4-20 UNC thread size with 7-inch length under head for long-reach bolting applications
• Grade 8 steel construction for high tensile strength in demanding bolted joints
• Partially threaded shank reduces galling risk and maintains clamping integrity in the grip zone
• Bright uncoated finish suitable for use with standard nuts and hardened washers
• Conforms to ASME B18.2.1 dimensional standards for consistent, specification-grade fitment
• 7/16-inch hex key size for standard socket or wrench installation

Compatibility

Designed as a specification-grade replacement or new-install fastener for any application requiring a 1/4-20 UNC hex head cap screw at 7 inches length under head, conforming to ASME B18.2.1.

Installation Notes

Installation should be performed by a qualified mechanic, technician, or tradesperson familiar with fastener torque requirements for Grade 8 hardware. Always use an appropriate hardened flat washer and Grade 8 nut to maintain the fastener's rated strength. Power down and de-energize any equipment before accessing bolted assemblies. Do not substitute lower-grade fasteners in joints specified for Grade 8 hardware.
