REDUCED PROFILE LOCKNUTS
Advanced Machine & Engineering Co. has announced a change to the locking screws used on the Type MSF locknuts. The previous Allen screws no longer are available with the MSF reduced-profile precision locknuts. The clamping screws are sold only with a hexalobular socket head, which is similar to a TORX system screw.
The new screws are designed to improve the handling, mounting and service life of the tools used for tightening the screws. The locknuts use the Spieth locking principle that provides vise-like locking of the locknut.
