Grip length is one of the most fundamental concepts in bolted joint design.

In this video, we break down exactly what grip length means across four common fastener configurations: studs in through-holes, studs in tapped holes, bolts in through-holes, and bolts in tapped holes.

Understanding grip length isn't just academic. It directly determines the free length of fastener under tension, which affects clamp load, joint integrity, and long-term reliability - especially in high-stakes industrial and defence applications.
