Metric Lock Washers
Metric lock washers are locking fasteners designed to prevent threaded fasteners, such as bolts and screws, from becoming unfastened. These washers prevent fasteners from unfastening by providing extra security against vibration and torque. There are many different types of lock washers; however, they all serve the same underlying purpose: to “lock” fasteners in place. While the most popular style of standard lock washers is the split washer, other styles include curved spring, serrated, high collar, or star lock washers.

Lock Washer Types from Metric & Multistandard
Standard Lock Washers
Standard lock washers, also known as split lock washers or round helical lock washers, are commonly used with hex head cap screws and hex nuts. These fasteners are ideal for general-purpose applications to prevent loosening from vibrations. We offer standard lock washers in a variety of sizes, ranging from 2mm to 72mm in diameter. Materials include:- Zinc-plated steel
- Stainless steel
- Bronze
Curved Spring Lock Washers
Curved spring lock washers are designed to help prevent loosening using a spring force. Their superior resistance to vibration is increasing their demand for high-stakes vibration applications. Available in diameters ranging from 2mm to 10mm, we offer curved spring lock washers in:- Steel zinc
- Stainless steel
High Collar Lock Washers
High collar lock washers provide increased security against high vibrations and torque, and are often used with machine screws or socket head cap screws. With small outer diameters, they can fit in tight spaces and rely on friction to prevent loosening. Our selection of high collar lock washers ranges in diameter from 3mm to 42mm. Available materials include:- Black steel
- Steel zinc
- Stainless steel
Serrated Lock Washers
Serrated lock washers feature serrated teeth that grab onto the fasteners’ mating surface to prevent loosening. Especially useful for high-vibration environments involving machinery, vehicles, or appliances, these washers dig into the material being fastened to resist rotation. Available in diameters ranging from 2mm to 30mm, we offer serrated lock washers in:- Zinc-plated steel
- Stainless steel
Star Lock Washers
Star lock washers are similar to serrated lock washers in that they feature serrated teeth that prevent loosening. However, star lock washers are available with both internal and external teeth, which can dig into both the material being fastened and the fastener itself. Ideal for high-vibration applications, we supply star lock washers with diameters ranging from 2mm to 30mm and in materials including:- Steel zinc
- Stainless steel
