The MS35338-45 Lock Washer is a military-standard split lock washer designed to prevent loosening of fasteners in aircraft, aerospace, and industrial mechanical assemblies. It provides spring tension against a nut or bolt head, helping maintain clamping force and resisting vibration-induced loosening in critical applications.

This washer is commonly used in aviation maintenance, engine assemblies, airframe structures, and other high-vibration environments where secure fastening is essential. It is supplied in a 100-piece pack for maintenance, repair, and overhaul (MRO) inventory use.

Its primary features include:
Manufactured to MS35338 military aerospace standards
Split lock washer design for anti-loosening performance
Helps maintain fastener preload under vibration
Suitable for aircraft structural and mechanical applications
Durable steel construction for high-strength performance
Corrosion-resistant coating depending on variant specification
Packaged in a 100-piece maintenance and workshop set
Compatible with aviation repair and overhaul procedures

Lock washers like the MS35338-45 are widely used in aerospace systems because they improve fastener security, reduce the risk of loosening under vibration, and support long-term mechanical reliability in demanding operating conditions.
