Bremick is an Australian-owned fastener manufacturer and distributor supplying bolts, nuts, screws, washers, threaded rods, socket screws, and anchoring products to construction, engineering, fabrication, and industrial maintenance operations across Australia. Bremick nylon insert lock nuts (Nyloc) provide a prevailing-torque locking action that resists loosening under vibration, used where a standard hex nut cannot be relied upon to stay at torque without additional retention. Where this product is used Bremick lock nut fasteners are used in structural steel, mechanical engineering, fabrication, and maintenance assembly applications across Australia. Vibrating machinery, automotive, and equipment assemblies where standard nuts can loosen under dynamic load. Safety-critical bolted joints requiring a prevailing-torque locking element without secondary locking hardware. Metric and imperial applications from light engineering to heavy-duty equipment maintenance. Key specifications Specification Detail Finish Zinc Plated Selecting the right option Nylon insert lock nuts are single-use — once removed and re-tightened, the nylon insert may not provide full locking torque. Select by thread size, pitch, and grade to match the bolt specification. Contact AIMS for all-metal prevailing-torque lock nuts (beam nuts) for high-temperature applications where nylon inserts are not suitable.
