Value Collection SEW8X1600-050BX M16 Lock Washer 17mm Id

Product Description

The VALUE COLLECTION SEW8X1600-050BX is an external tooth lock washer designed for use with M16 fasteners in industrial, mechanical, and structural assembly applications. Manufactured from Grade 18-8 austenitic stainless steel (A2), this washer features a serrated external tooth profile that bites into the mating surface and fastener head to resist loosening caused by vibration and dynamic loads. With a 17mm inside diameter, 26mm outside diameter, and 1.2mm thickness, it delivers consistent locking performance without coatings or platings that could affect dimensional tolerances. Sold in a minimum order quantity of 50 pieces per order.

This external tooth lock washer is suited for M16 bolt and screw assemblies in corrosion-prone environments where stainless steel is specified, such as marine, food processing, chemical processing, and outdoor structural applications. The austenitic A2 grade provides solid corrosion resistance across a wide range of service conditions. It is installed by trade mechanics, millwrights, maintenance technicians, and assembly professionals working with stainless fastener systems that require reliable anti-loosening hardware. Conforms to DIN 6797 and DIN 6798 standards.

Compatibility

Designed for use with M16 screws and bolts. Conforms to DIN 6797 and DIN 6798 standards for external tooth lock washers.

Installation Notes

Installation is performed by mechanics, millwrights, or assembly technicians using standard hand or power tools. Always de-energize, depressurize, or otherwise make safe any equipment before servicing fastener assemblies. Place the washer between the fastener head and the mating surface with the teeth facing the fastener head for proper locking engagement. Do not reuse lock washers that have been fully compressed or deformed, as the locking function is reduced after initial set.
