GP-Star Versatile Quick-Release Thumbscrew Set
GP-Star Versatile Quick-Release Thumbscrew Set
Meet the GP Star Bolt — a tool-free, star-shaped thumbscrew designed to make hardtop removal fast, secure, and frustration-free. Made with a galvanized coated metal screw with an M8-1.25 thread, topped with an Engineered ABS star head with reinforced Nylon, it’s a direct replacement for factory hardtop bolts on Jeep Wrangler, Gladiator, and Ford Bronco models, plus any DIY project with 8mm+ mounting holes. The signature star head isn’t just functional—it adds a subtle badge-style detail that lets you customize your vehicle with a clean, purposeful look.

Ford Bronco soft top note: The Bronco tub-edge packs are for hardtop Broncos. A soft top covers the Bronco tub edge, so they do not fit; soft-top Bronco owners can use the Anchor or the GP-Star at the C-pillar mount for bags, coolers and tools.

Jeep Wrangler JK and JL, Jeep Gladiator JT, and the 2021+ Ford Bronco (Bronco Bolt Set).

Jeep sets are 6, the Gladiator set is 8, and Bronco sets are 8.
What thread size and torque?
M8-1.25 × 25 mm. Torque is 158 in-lb each: hand-tighten until snug with the rubber washer first, and do not over-force.
