Tang-Type Wire Inserts

Tang-Type Wire Inserts: Aerospace to Construction Thread Reinforcement for Extreme Environments

Tang-type wire thread inserts (standard wire inserts) deliver mission-critical thread reinforcement across industries where failure is not an option. Engineered from cold-rolled 18-8 stainless steel with diamond-coil geometry, they boost thread strength by 300% while providing vibration resistance exceeding MIL-STD-1312 requirements. From rocket engine mounts to seismic bridge joints, these inserts solve stripping, corrosion, and cross-threading failures.
