Toothed Lock Washers - Type V, Countersunk with External Teeth&Countersunk external toothed lock washer for assembly

A taper washer is a commonly used sealing element that works by utilizing the special shape of a taper to form a reliable seal with the surface of the corresponding part. Tapered washers are widely used in many industrial fields, such as automotive, machinery, aerospace, and other industries.
The special shape of a tapered washer is the key to its sealing action. The inner and outer diameters of the washer each exhibit a tapered shape, typically 60 degrees, and this shape allows the washer to catch the loose parts around it when under pressure, forming a seal. At the same time, the number of oblique angles and the amount of compression of the tapered washers are designed according to strict requirements to ensure their sealing performance.
The sealing principle of a tapered washer is realized by being compressed. When the gasket is pressurized, it shrinks inward along a number of oblique angles, compressing the surface around it to achieve the sealing effect. During use, the amount of compression and sealing effect of a gasket will vary depending on the operating conditions. Therefore, it is usually necessary to choose different gasket materials and sealing methods according to the specific situation.
Tapered washers also have many advantages, such as high-temperature resistance, chemical resistance, pressure resistance, and so on. These advantages make taper washers widely used in the industrial field. For example, in automotive manufacturing, tapered washers are used to seal engine components, fuel tank transmission systems, etc.; in machinery manufacturing, tapered washers are used to seal machine tool spindles, bearings, and pumps; in the aerospace field, tapered washers are used to seal engines, hydraulic systems, and hatches.
The taper washer is a very practical sealing element, which is realized by the taper shape and compression. In practical application, it is necessary to choose the appropriate gasket material and sealing method according to different working conditions to ensure its sealing effect. Tapered washers are widely used in automotive, machinery, aerospace, and other fields, and their advantages include high-temperature resistance, chemical resistance, pressure resistance, and so on.    

Internal-/External-Tooth Lock Washers. The combination of internal and external teeth boosts gripping power to maintain a tight hold and provide more vibration resistance than other toothlock washers. Use with fasteners that have heads large enough to make contact with the external teeth, such as pan, button, and binding head screws.
Black-oxide steel washers are mildly corrosion resistant in dry environments. Zinc-plated steel washers are corrosion-resistant in wet environments.
410 stainless steel washers have excellent wear resistance.Countersunk Tight-Grip External-Tooth Lock Washers. To keep 90° countersunk screws from loosening in vibration applications, the teeth on these washers bite further into the screw head and joint than standard external-tooth lock washers for a more secure hold. Made of zinc-plated steel, these washers resist corrosion in wet environments. All meet DIN dimensional standards.
