Black Oxide Stainless Steel Lock Washers
Medium Profile Split Ring Lock Washers
Split ring lock washers are used to prevent nuts, bolts, and screws from vibrating loose. Lock washers are split at a certain point and bent giving them a helical shape. These lock washers are compressed during installation adding extra pressure to the nut or bolt and material. This extra pressure creates a resistance to rotation. The edges or the split may add extra holding power by digging into the nut. Split ring lock washers are used where constant vibration occurs.

Black Oxide 18-8 Stainless Steel WashersStainless Steel Lock Washers, also known as Split Ring Lock Washers, Locking Washers or Spring Lock Washers, in this selection are made of 18-8 stainless steel, with a black oxide finish. Black Oxide Fasteners made from stainless steel, have been chemically treated to alter certain qualities of the material, most notably the color. The treatment also adds a mild corrosion and abrasion resistance (in addition to the plain stainless steel’s nature), and reduces the now black oxide stainless steel fastener’s reflective properties. |
Split RingThe split ring style is perhaps the most common style of lock washer. The helical shape of the washer exerts force between the fastener and the installation surface, resulting in a bolt or nut that becomes resistant to loosening due to vibration. Additionally, the edges of the split may add additional resistance to movement by digging into the fastener and the installation surface. |
Medium ProfileSplit ring lock washers come in a variety of different thickness standards, however the medium profile thickness is the most common. Please note that the thickness referred to the metal of the washer itself, as the angle of the spring can change with use. |
