Lock Washers

Description

Lock Washers Lock Washers – High-Tension Fasteners for Secure and Vibration-Resistant Joints Split Ring Lock Washers are a critical component in mechanical and structural assemblies where bolt security is paramount. These washers are constructed from durable zinc-plated steel, which provides essential corrosion resistance for long-term use. When a nut or bolt is tightened over this washer, the split ring deforms and its sharp, biting edges mechanically lock the fastener in place. This creates a spring tension that actively maintains the clamping load and resists any tendency for the fastener to loosen due to vibration, dynamic load, or thermal expansion/contraction. The washers are available in a range of common medium-to-large imperial diameters, including 3/8″, 1/2″, 5/8″, and 3/4″, making them highly versatile for various industrial and automotive applications. Key Benefits Vibration Resistance: Mechanically locks the nut and bolt together, preventing rotation and loosening caused by dynamic load or vibration. High Tension: Provides a continuous spring force that maintains clamping load even when the joint experiences minor dimensional changes. Corrosion Resistance: Zinc plating protects the high-carbon steel from rust and weathering, ensuring joint longevity. Wide Size Coverage: Available in common medium-to-large imperial diameters (3/8″, 1/2″, 5/8″, 3/4″) for varied applications. Easy Installation: Simple to install beneath the bolt head or nut. Technical Specifications Product Type: Split Ring Lock Washer / Helical Spring Washer Sizes Available: 3/8″, 1/2″, 5/8″, 3/4″ (Inner Diameter) Material: Steel Design: Single Coil Split Ring Application: Vibration Prevention, Maintaining Joint Tension Grade: Industrial/Mechanical Perfect For Securing critical fasteners on engines, industrial pumps, and vibrating machinery. Structural steel connections in construction and bridge building. Automotive chassis and suspension assembly. Any bolted joint that must remain tight and secure over time. Application Instructions Placement: Place one lock washer beneath the nut or the bolt head. Tightening: Tighten the fastener to the proper torque specification. The washer will compress, and its sharp ends will bite into the bearing surface. Checking: Ensure the washer is completely flat after tightening (if it is not flat, the fastener is under-torqued). Safety: Use a flat washer beneath the lock washer if the bearing surface is soft (e.g., wood or soft plastic). Pro Tips Do not reuse a lock washer; once fully compressed, its spring tension is significantly compromised. Clean the fastener threads before installation to ensure accurate torque readings and maximum locking effectiveness. For added security in extreme environments, consider using a thread locking compound in conjunction with the lock washer. Store unused washers in a dry environment to maintain the integrity of the zinc plating.
