Miller’s Grade 8 Lock Pin Gets Even Tougher

For over 50 years, the Miller team has been at the leading edge of CNC machining and custom CNC machined products. Our Grade 8 Lock Pin, touted as one of the highest quality, strongest lock pin on the market, has been improved with a new zinc-rich base coat, making it even tougher.miller-grade-8-lock-pin_050119

The characteristic Miller dark gray Grade 8 Pin coating improves performance and stability of the pin across all tests from stress tests to corrosion resistance and more. This new coating is applied using industry best practices. You may also custom order this pin with our standard clear or yellow zinc. This gives you a variety of finishes to choose from for your lock pin.

These lock pins are ideal for lawn and gardening, DIY, farming, truck, and towing applications! If you have lock pin needs that require the highest of corrosion protection and confidence in torque / tension scenarios, the Miller Grade 8 Lock pin is your smartest option.

Miller offers the Grade 8 Lock Pin in a variety of sizes and finishes. You can go to the Single Wire Lock Pin product page for more information or click on the “Request a Quote” button below.
