These Hex head locking flange bolts are specifically designed to secure wood panels (including PKS panels) to PKS fittings. They're able to be tightened/loosened with the same size hex key that the fittings set screw uses, which makes these a must have for Parkour gyms.
The locking flange means that you may be able to skip using a lock washer and still have excellent performance long term, even on obstacles that are constantly vibrating from athlete movement. They fit perfectly into PKS T-Nuts, making a clamping system that cannot be beaten!
As always, gyms should regularly check equipment for hardware clamping strength and general wear. Cannot guarantee non-PKS fittings fitment, but they may work in many cases.
