Value Collection SEW8XX1400-050BX M14 Lock Washer 50pk

Product Description

The VALUE COLLECTION SEW8XX1400-050BX is a stainless steel external tooth lock washer designed for use with M14 fasteners. It features a 15mm inside diameter and 24mm outside diameter with a 1mm thickness. The serrated external teeth bite into the mating surface and fastener head to resist loosening caused by vibration and torque. Manufactured from Grade 316 austenitic stainless steel (A4 classification), this washer provides strong corrosion resistance in wet, marine, and chemically aggressive environments. It ships uncoated and is sold in a minimum order quantity of 50 pieces. Electricians, plumbers, millwrights, and mechanical contractors use these washers in structural and equipment assembly applications.

This external tooth lock washer is suited for residential, commercial, and industrial fastening applications where vibration or dynamic loading is present. It is appropriate for use in marine hardware, food processing equipment, chemical processing assemblies, outdoor structural connections, and any application where corrosion resistance is a priority. The M14 sizing makes it compatible with standard metric fastener assemblies using M14 screws or bolts. Meets DIN 6797 and DIN 6798 standards. This washer does not meet military specifications.

Installation Notes

Installation is performed by machinists, millwrights, plumbers, or electricians depending on the application. Place the washer with the teeth facing the fastener head or the mating surface — not between two flat surfaces — to allow the teeth to engage properly. Ensure mating surfaces are clean and free of grease where locking action is required. Follow applicable mechanical or structural codes for fastener torque sequences in the specific assembly context.
