Product Information

Riveting is the process of applying force to two materials to join them together, manually or using a machine. If the joint’s surface isn’t smooth, the screw is more likely to compress higher places over time and become loose. Metallic coatings – Typical coatings used to produce corrosion resistant washers are zinc, cadmium, and nickel. DIN (Deutsches Institut für Normung - German Institute for Standardization) standards are issued for a variety of components including industrial fasteners as Metric DIN 125 Flat Washers.

Coatings can be used to reduce wear and friction, either by hardening the surface or by providing a solid lubricant (i. Liquid-sealing washers are made of a soft substance that may press entirely against the object’s surface. Each washer is good for close to 1 1/2 turns for just-right timing and is made of black carbon steel. The reason was that the flat copper washers I was using for the oil plug were leaking unless I really cranked down on them, and I do not want to strip the oil pan threads.Washers are also important for preventing galvanic corrosion, particularly by insulating steel screws from aluminium surfaces. Specifications for standard metric flat washers were known as DIN 125 (withdrawn) and replaced with ISO 7089. JP Enterprises' Crush Washers offer a quick and painless installation of comps, without the struggle of traditional washers. DIN standards continue to be used for parts which do not have ISO equivalents or for which there is no need for standardization. While generally more expensive per piece, these washers provide the highest amount of vibrational loosening prevention.

Made of stainless steel with a silver finish, these washers have a US Patent Number 100,041,753 and are a necessary addition to any comp installation kit. These washers are made of stainless steel, auto-center, and provide smooth and consistent crush without struggle. The Double Crush Washers auto-center and provide smooth, consistent crush, making them a better alternative to the "necessary evil" of traditional washers. They are preferred over similar, more expensive, heavier, and larger springs that take up more space. Each washer is good for close to 1 1/2 turns, ensuring just-right timing for your comp installation.The crush washer should be inserted by hand, and its edges should line up with the fasteners and not go over them. I would say any energy spent on any facet of the subject is wasted, including this post as nobody is going to change what they do or think because of it. a b Bowmans Fastener Technical Fast of 1999 on page 32 and 33 has SAE recommendation from 1969 that lock washers not be used in any critical application.
