Jack Bolt Steel 11in Coarse Thread 10pk

The Jack Bolt Steel 11in Coarse Thread 10pk from Allstar Performance is an essential fastener solution for serious automotive builders and mechanics who demand reliable, repeatable clamping in high-vibration engine compartments. Jack bolts serve as critical lifting and positioning anchors during engine teardowns, rebuilds, and transmission work—holding components securely while allowing controlled vertical movement. This ten-pack ensures you maintain a full kit of backup fasteners for frame-up restorations, engine swaps, and fabrication projects where precision engagement and tool longevity matter.

Each 11-inch steel bolt features a coarse thread that grips tapped aluminum and cast-iron blocks without galling, making reinstallation quick and damage-free across multiple teardown cycles. The coarse thread geometry reduces stress concentration at the root radius, delivering superior tensile strength under the repetitive clamping loads encountered during engine assembly and removal sequences. Steel construction resists the thermal cycling and chemical exposure inherent in engine bay environments, while the 11-inch length accommodates standard engine lifting brackets and aftermarket hoist fixtures without requiring spacers or adapters.

Professional rebuilders, race teams, and dedicated DIY enthusiasts benefit most from maintaining a dedicated set of jack bolts, as field-worn or cross-threaded fasteners compromise safety during overhead lifting operations. This product is designed to meet the rigorous demands of engine work, ensuring reliability and safety in critical applications. With a full ten-pack, users can ensure they have the necessary fasteners for any project.
