Repeated firing and transport create extreme shock and vibration, causing joints to loosen and affect accuracy and safety. Nord-Lock® wedge-locking washers secure the joint and maintain clamp load under dynamic conditions.

Shock, recoil, and vibration can reduce preload, leading to joint instability and increased wear. Superbolt® multi-jackbolt tensioners deliver high and uniform preload for stable and reliable performance.

Discover Superbolt® tensioners

Large fasteners require high preload, but conventional methods often result in uneven or insufficient tension. Superbolt® tensioners enable precise preload using low installation torque, ensuring reliable joint integrity.

Limited access in turrets and structures makes installation difficult and increases the risk of improper tightening. Superbolt® tensioners use simple hand tools, enabling safer and more reliable installation in restricted spaces.

Dynamic loads can cause joints to loosen over time, increasing maintenance and reducing system reliability. Nord-Lock® washers prevent loosening and maintain clamp load, supporting long-term performance.

Defense applications require proven performance under extreme conditions. Nord-Lock Group solutions are tested according to key military shock and vibration standards, including MIL‑STD‑901D and NASM 1312‑7, as well as UK MOD Def Stan 00‑35. NSN and NCAGE codes support secure, compliant sourcing for artillery and weapon systems.
