SIMMONDS®, a business unit of  HOWMET AEROSPACE, specialises on self-locking and special nuts. 

The SIMMONDS® self locking nuts come in different types (series) offered in different materials and sizes, they can be reused (fully tightened and loosened) at least 15 times without affecting the nut's performanceare, they are lightweight and extremely durable, , exhibit a  very strong locking performance and can be used in a wide temperature range.

The SIMMONDS® Nylstop Type P (Standard Version) and Type T (Low Profile Version) nylon locking nuts have been designed to stop nut and bolt disengagement during use. The internal nylon ring deforms around the threads as the nut is twisted on to the bolt, ensuring a tight, vibration resistant grip on the bolt.

The SIMMONDS® PH Series Aerospace quality hexagonal self-locking nuts are small, thin walled, lightweight and extremely strong. Made from  CRES A286 stainless steel and silver plated these nutls are particularly useful when space and weight are at a premium. Used typically in engine applications they are MJ threaded and offered in Meric diameters M3-M12 to meet different applications requirements. 

The SIMMONDS® MHT Series are conical shaped self locking nuts, where the diameter of the upper part of the nut is slightly reduced. Six vertical slots will open gradually whilst the nut is screwed onto the bolt. The elasticity provided by the particular shape of the nut will ensure the required locking torque.
