At Impress Group we offer a standard range of threaded Pal nut lock nuts which incorporate a design principle that has stood the test of time over 60 years. These pal nuts can be used alone for load-carrying in light-duty assemblies or they may be used in addition to standard nuts to guarantee the tension of high-stress assemblies.

We manufacture Pal Nuts in-house which means we can surpass most stockists offering bespoke non-standard sizes and we offer Palnuts from any material including 316 Stainless Steel, Duplex (UNS 32750, UNS 32760), Hastelloy, Monel Inconel and Phosphor Bronze.

The material used on our Pal nuts can be certified to a 3.1 certificate according to EN 10204:2004 that declares the 'metallic products' are in compliance with the order requirements.
