Boker’s, a leading manufacturer of precision metal stampings, washers, spacers and shims, offers complete production of non-standard and customized lock washers and tab washers designed to provide secure fastening in your essential applications. These types 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 turning, slipping or loosening 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,” said Chuck Kersey, Assistant Sales Manager. “Coupled with immediate access to over 2,000 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.”
