Repeated firing and transport expose joints to high shock and vibration. This can cause bolted joints to loosen or lose preload over time, leading to misalignment, reduced accuracy, increased maintenance and potential failure during critical operation. Nord-Lock® wedge-locking washers secure bolted joints mechanically, maintaining clamp load and preventing loosening in artillery and weapon systems.

Shock, recoil, and vibration can cause preload to decrease over time, leading to joint instability, uneven load distribution, and increased wear. Superbolt® multi‑jackbolt tensioners deliver high and uniform preload, ensuring stable joints and reliable performance in demanding artillery and weapon systems.

Large diameter fasteners in artillery systems require very high preload to ensure structural integrity. Conventional tightening methods can make it difficult to achieve sufficient and accurate preload, leading to uneven load distribution and increased risk of joint failure. Superbolt® tensioners enable precise and controlled tensioning using low installation torque, ensuring reliable and uniform preload.

Limited access is common in turrets and structural assemblies. Conventional tightening methods often require bulky tools and high torque, making installation difficult and increasing the risk of improper preload and safety issues. Superbolt® tensioners use simple hand tools, enabling safer, faster, and more reliable installation and maintenance in restricted spaces.

Dynamic loads from shock, recoil, and vibration can cause bolted joints to loosen or lose preload over time. This leads to joint instability, increased maintenance requirements, and reduced system reliability. Nord-Lock® washers prevent loosening under dynamic loads, maintaining clamp load and supporting long-term reliability in artillery and weapon systems.

Defense applications require proven performance under extreme conditions. Nord-Lock® 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.
