Self-locking nuts

Promoted by Bulte Plastics as being "suitable for applications that require extra security" a new range of self-locking nuts is said to be able to eliminate backlash without sacrificing efficiency.

"This type of nut is more effective than standard hexagon nuts because it includes a non-threaded part which closes around the thread thus creating a lock between the two threads."

The nuts are manufactured from polyamide 6.6 that, when combined with steel screws, provides low drag torque and smooth operation throughout the life of the assembly. In addition to being used as a secure fastening for joining many kinds of parts the products are stated to save weight compared with conventional steel/nylon lock-nuts.

Sizes include M5, M6, M8, M10, and M12. The working temperature range is from -30ºC to +100ºC
