Stanley Engineered Fastening now incorporates its self-locking Spiralock internal thread form design, which reportedly has superior resistance against self-loosening when exposed to harsh environments involving significant shock, extreme vibration, and drastic thermal cycling, into key locking threaded inserts.

Threadsize Calculator

An iPhone App capable of calculating the exact diameter of drill required for precise thread-creation operations has been developed by cutting tool specialist Dormer Tools. The "Dormer Tools Threadsize Calculator" has been designed by Dormer to help engineers and machinists quickly and accurately select the optimum drill diameter needed to create a thread.
