Boker’s, a leading manufacturer of precision metal stampings, washers, spacers and shims, offers a complete range of non-standard and customised lock and tab washers designed for secure fastening in essential applications. These kinds of washers are vital in applications subjected to vibration, torque, heat or corrosion, providing an additional security measure to restrict threaded nuts, bolts or fastening systems from loosening, slipping or turning under load.
Lock washers are widely used as a reliable method to secure fastening. Common designs include internal tooth, external tooth or combination internal and external tooth designs. Lock washers exert a load, partially deform and lock a fastener in place. Tab washers are an additional form of lock washer that features one or more internal or external notches or tabs designed to hold the nut in place in relation to the connecting bolt or stud. Tabs may be bent or engage into keyways or slots in connected surfaces to provide a positive locking surface. In some applications, they are deployed along with a flat washer in order to distribute the load evenly without deforming the assembly that the fastener is secured to.
“As a leading manufacturer of precision metal stampings and washers, Boker’s provides production capabilities for countless non-standard lock and tab washer configurations, as well as completely unique, custom designs for any application demands,” Boker’s Assistant Sales Manager Chuck Kersey says. “Coupled with immediate access to over 2000 materials and one of the industry’s widest range of sizes and thicknesses, we can help OEMs produce virtually any high-performance tab washer design they can envision.”
