- Nord-Lock® Wedge Washers secure bolts with tension instead of friction. The system cannot loosen unintentionally as it creates a wedge-effect underneath the bolt head or nut. The system comprises of a pair of wedge-lock washers with cams on one side and radial teeth on the opposite side
- Nord-Lock® offer the following advantages: Will not loosen under severe vibration or heavy dynamic loads > Reliable locking, even for joints with short clamp length > Quick and easy to install and remove > When untightening you can hear a click > High corrosion resistance with Delta Protekt® and Stainless Steel A4-70 G316 > Locking function not affected by lubrication > Reusable
- Traceability: Washers are laser marked with Nord-Lock brand name, control number and type code for traceability
- Understanding and measuring washer sizing: Washer sizes can be a little confusing. M6 suits a M6 bolt. The inside diameter of a M6 washer is greater than 6mm to allow the washer to fit over the bolt
- Are Metric & Imperial Washers Interchangeable?: In most cases they are which is why we have added metric sizing to the imperial range and imperial sizing to the metric range. If you are still unsure or if the washer dimensions are critical click on the washer you are interested in and view the technical specifications table before ordering
- Dimensions: Our stock is genuine Nord-Lock® product, sourced from Hobson Engineering, the Australian Distributor of Nord-Lock® Washers. Although the supply is consistent minor differences may exist between batches such as inside dimensions, outside thickness, visible stamping, appearance, packaging and actual finish
- Material / Coating: Marine Grade Stainless Steel A4-70 G316 is the ultimate corrosion resistance fastener. Designed to be used in all conditions. It is the best material to use in marine, coastal, chemical and food environments. Stainless steels are largely non-magnetic, but it is not uncommon for some stainless steel fasteners, especially stamped components like washers to show a small degree of magnetism. This is partly due to the work-hardening of the product during the manufacturing process. Marine Grade Stainless Steel A4-70 G316 can be easily identified by the following markings: A4, A4-70, A4-80, 316 or G316. Small sized washers are generally not stamped
- Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
