MS35333-41P Military Spec Internal Tooth Lock Washer (5/16", Cadmium Plated Steel)

When you need an unyielding grip that stands up to vibration and dynamic loads, the MS35333-41P Internal Tooth Lock Washer is your go-to solution. Manufactured to stringent Military Standard (MS) specifications, this washer is an essential component for critical assemblies in aerospace, defense, automotive, and industrial sectors where fastener security is paramount.

The MS35333-41P is a Type A, internal tooth lock washer, specifically designed for use with 5/16" nominal diameter fasteners. Its unique internal teeth bite into both the fastener head/nut and the mating surface, creating a positive lock that resists loosening due to vibration, thermal expansion, and contraction.

Crafted from high-quality steel and featuring a cadmium plating (often Type II, Class 3 per QQ-P-416), this washer offers excellent corrosion resistance, making it suitable for harsh environments. The "P" suffix commonly denotes this protective plating. This combination of mechanical locking and corrosion protection ensures the longevity and integrity of your assemblies.

Key Features & Benefits:

• Military Standard (MS) Certified: Produced and inspected to rigorous MS35333 specifications, guaranteeing consistent quality, performance, and reliability for critical applications.

• Positive Locking Action: Internal teeth provide a strong, resilient grip that prevents fastener loosening from vibration and torque.

• Corrosion Resistant: Cadmium plating (as indicated by the "P" suffix and common practice for this part) offers superior protection against rust and corrosion, extending the life of your connections.

   

• High-Strength Steel: Made from durable steel, ensuring the washer maintains its spring tension and locking ability under pressure.

• Designed for 5/16" Fasteners: Precisely sized to fit 5/16-inch bolts and screws, providing optimal engagement.

• Versatile Applications: Ideal for use in aircraft, military vehicles, heavy machinery, and any application requiring enhanced fastener security and durability.

• Supersedes AN936A516: This part number often supersedes or is equivalent to the older AN936A516 standard.

• NSN: Commonly associated with NSNs like 5310-00-167-0721 or similar for government procurement.

Add an extra layer of security and reliability to your critical fastenings. Choose the MS35333-41P Military Spec Internal Tooth Lock Washer for peace of mind.
