Value Collection 403260BR Hex Head Cap Screw 5/8-11 X 8 in

Product Description

The VALUE COLLECTION 403260BR is a partially threaded hex head cap screw designed for general-purpose fastening in mechanical, structural, and industrial assembly applications. Manufactured from Grade 2 steel with a zinc-plated finish, this fastener measures 5/8-11 thread size with an 8-inch length under the head. The zinc coating provides basic corrosion resistance suited for indoor and sheltered environments. At 0.7 pounds, this is a substantial fastener appropriate for medium-load bolted connections where full threading is not required. A 15/16-inch hex key size is required for installation and removal.

This cap screw is well suited for use in fabrication shops, light manufacturing, HVAC equipment mounting, plumbing support structures, and general mechanical assembly where UNC inch-series fasteners are specified. Partial threading allows for a smooth shank section, which is preferred in applications requiring a precise bearing surface or where bolts pass through clearance holes before engaging a tapped bore or nut. Minimum order quantity is 10 pieces.

Key Features

• 5/8-11 UNC thread size for compatibility with standard inch-series tapped holes and nuts
• 8-inch length under head with partial threading for shank-bearing applications
• Grade 2 steel construction for general-purpose medium-strength fastening
• Zinc-plated finish provides baseline corrosion resistance in dry or sheltered conditions
• 15/16-inch hex drive size compatible with standard wrenches and sockets
• Weighs 0.7 pounds per piece — suitable for structural bolted connections

Compatibility

Designed as a standard UNC inch-series hex head cap screw compatible with 5/8-11 tapped holes and standard hex nuts in general mechanical and structural assemblies.

Installation Notes

Installation is performed by millwrights, maintenance technicians, and general tradespeople using a 15/16-inch wrench or socket. Always ensure the mating tapped hole or nut is free of debris and the thread class matches before driving the fastener. Do not use impact tools at full power on Grade 2 fasteners without confirming torque requirements for the specific joint. Follow applicable industry or facility torque specifications for 5/8-11 Grade 2 fasteners as outlined in the relevant assembly documentation.
