Self-locking fasteners in Waltham, MassachusettsSelf-locking fasteners, also known as self-clinching fasteners, are a class of fasteners that, once threaded into a softer, ductile metal, is held in place by means of a serrated clinching ring, knurl, ribs, or hex head which prevents the fastener from turning in the host material, effectively locking it so that it can’t be removed. Properly installed, self-locking fasteners become a permanent part of the assembly.

Self-locking threaded fasteners have a number of advantages over other kinds of fasteners, including greater reliability and holding power. They are used primarily in situations where good pullout and torque loads are required, especially in thin sheet metal that can’t be securely fastened by other means. In many cases, threaded self-locking fasteners – because of their locking power, low profile, and compact design – can enable the use of even thinner sheet metal for a lighter and smaller assembly form factor.

Self-locking fasteners from Waltham, Massachusetts are the perfect fastening solution for applications in which the attaching hardware can’t be easily reached after a cabinet, chassis, or other component is assembled. Self-clinching threaded fasteners can be installed during fabrication to simplify and speed up assembly operations and component mounting, especially for equipment installations and replacements performed in the field.

Threaded self-locking fasteners from Waltham, Massachusetts should only be used in products utilizing a metal that is softer than the fastener. For a self-locking fastener to work correctly it must cold-flow the softer sheet material to form a secure bond. If the self-clinching fastener is softer than the sheet metal, it will simply deform and not work properly. Products incorporating stainless steel sheet metal require self-locking fasteners designed specifically for stainless.

Waltham, Massachusetts self-clinching fasteners are ideal for manufacturing products in which simplified assembly and fewer parts can reduce production costs and speed up time-to-market in highly competitive marketplaces. Fasteners that self-lock not only reduce labor time, inventory and overall product weight, they also provide greater product design freedom enabling the use of thinner metals. All of this makes self-locking threaded fasteners produced in Waltham, Massachusetts especially attractive for medical, computer, communications, automotive and aerospace products.
