SGL-F

SGL-F Flank Locking. The SGL-F Series locknuts employ 30°, 3 point locking. The outstanding design of the brass threads are perfectly matched and prevent any loosening whatsoever. 30° design locking screws also reduce torque on this product. Clamping rims, trailing rims, and outer skirts are all precision ground to conform to the high precision requirements of high rpms.

SGL-R

SGL-R Radial Locking. The SGL-R Series Locknuts employ 3-way radial locking. Thickness is comparatively thinner than other products. This series is especially applicable for use when locknut space is limited. Aside from where other products are not usable due to space restrictions, locknut threads, clamping rims, trailing rims, and outer skirts are all precision ground to conform to the high precision requirements of high rpms.

SGL-A

SGL-A Axial Locking. This locknut employs 3 way axial locking with the same thickness as the SGL-F series. 3 way axial locking is especially applicable to assembly work within special space constraints. Locknut threads, clamping rims, trailing rims, and outer skirts are all precision ground to conform to the high precision requirements of high rpms.

SGL-K

SGL-K Clasp Locking. The SGL-K Series locknuts utilize the elasticity of the steel body itself, axial locking, and forced locking. With locking capabilities more than three times higher compared to traditional locknuts, this series is aimed at harsh working conditions where locknuts are easily loosened. Locknut threads, clamping rims, trailing rims, and outer skirts are all precision ground to conform to the high precision requirements of high rpms.
