You found the perfect attachment. You cut the uprights. You've got everything lined up, and then you realize you can't find the right bolts anywhere.
M24-size hardware at 110mm length isn't something most hardware stores keep in stock. It's a metric spec at a length that falls squarely between what's on the shelf and what's special-order. Most people end up improvising with the wrong size, over-tightening undersized bolts, or waiting a week for an online order to arrive from a random overseas seller.
These bolt sets exist to solve exactly that problem. They're sized precisely for 3x3 steel tubing with 1" holes, the standard spec on most premium squat racks and power racks on the market, including Fringe Sport's own lineup. Whether you're building a rack extension, connecting uprights together, or securing custom fabrications to your existing rig, the M24x110mm is the bolt you need.
Each set includes the full hardware components: bolt, nut, flat washer, and lock washer. The flat washer spreads clamping load across the steel surface. The lock washer keeps everything tight under vibration and repeated loading. Nothing will rattle loose.
Order the quantity that matches your project, or grab extras. You'll be glad you have them.

These are designed for 3x3 steel tubing with 1" holes, the standard spec on most premium squat racks and power racks, including all Fringe Sport racks. If you're unsure, measure your hole diameter. If it's 1", you're good to go.
Most premium rack manufacturers use metric hardware, including Fringe Sport. M24 is the correct diameter for 1" hole uprights, providing the proper fit and clamping surface without play in the joint.
It depends on your project. A single upright-to-upright connection typically uses 2 to 4 bolts. A full extension on both sides of a rack usually calls for 8. When in doubt, order more. Unused bolt sets keep.
These are intended for steel-to-steel rack connections, not concrete anchoring. For floor anchoring, you'll want dedicated concrete anchor bolts rated for that application.
You'll need a wrench or socket that fits an M24 hex head (typically 36mm). Torque to manufacturer spec for your specific connection.
