The ALLSTAR PERFORMANCE Jack Bolt Collar 1-1/8in-12 10-pack (SKU ALL56098-10) is a precision fastener assembly designed for high-vibration mechanical applications where secure, repeatable clamping is non-negotiable. Each collar features a 1-3/8-inch tall profile with a 1-5/8-inch outer diameter, engineered to work with 1-1/8-inch-12 threaded fasteners. This 10-pack delivers the redundancy and inventory depth professional builders, fabricators, and mobile technicians require for field service, vehicle restoration, and production assembly work.
Steel construction with a natural finish provides corrosion resistance suitable for indoor and protected outdoor environments. The collar design distributes clamping force across a wider bearing surface than standard washers alone, reducing stress concentration and fastener loosening caused by vibration, thermal cycling, or repeated loading. The 1-1/8-12 thread specification matches common fastener sizes found in industrial equipment, automotive suspension systems, machinery mounting, and structural fabrication. With a combined pack weight of 4.98 pounds, ten collars deliver substantial material value for applications requiring batch fastening or replacement stock.
Technicians managing heavy equipment, off-road vehicle builds, motorsport projects, or industrial maintenance rely on quality collars to ensure joint integrity under demanding conditions. The 10-pack format serves workshop inventory needs, vehicle restoration shops, fabrication facilities, and field service crews who stock consumables for rapid deployment. Whether securing suspension components, engine block assemblies, frame reinforcements, or machinery housings, consistent fastener quality across a full job minimizes rework and callback issues.
ALLSTAR PERFORMANCE specializes in mechanical fastening systems and assembly hardware, positioning this collar within a market segment emphasizing reliability for performance and industrial applications where fastener failure carries cost and safety consequences.
