PRECISION ARMAMENT's AR .308 5/8-24" ACCU-WASHER SYSTEM is a set of precisely machined stainless steel washers that allow accurate indexing of muzzle brakes and flash hiders without the need for peel or crush washers. The washers finally arrived and oil changed yesterday. All seemed to go OK but noticed a small trace of emulsification on top of the oil once finished. We’ve highlighted some functions of washers, but we’ll now discuss them in full detail.

I have a long run planned for Monday and don't want to damage the engine. I'm hoping once it gets really hot this will disappear but is it safe to do so or should I 'bite the bullet' and buy some more oil and change it again and throw the new but contaminated oil away? Tab washers : Tab washers have a single tab or several tabs and notches that contour to fit around bolts and nuts. Sometimes, they lie flat. Tab washers are perfect for difficult areas, as they can withstand high temperatures and vibrations.In fact everything went smoothly until re-fitting the drain plug when it was obvious that the washer I had been given was much bigger than the old one. Unfortunately I didn't notice this until damaging the old one getting it off the bolt! A type of washer used in a variety of torque sensitive applications, designed to limit torque to a predetermined level and not beyond. To appreciate what crush washers are, we’ll need to understand the concept of washers in general. So, what are washers? What Are Washers?

JP Enterprises has designed a better alternative to traditional crush washers, the Double Crush Washer, for easy and consistent comp installation.

Fasteners such as screws and bolts hold components of instruments together. However, they can sometimes put too much pressure on the fastening object. The S.I. crush washers are great for replacing your used ones and for installing a new muzzle device onto your AR. These high-quality components will provide excellent fit and reliable function in your AR series rifle.

These washers are made of stainless steel, auto-center, and provide smooth and consistent crush without struggle. John Holloway (2010). Illustrated Theatre Production Guide. Focal Press. p.202. ISBN 9780240812045.Used to electrically isolate a mounting screw from the surface it secures. Often made of nylon, these are also made of teflon, PEEK or other plastics to withstand higher temperatures. Phosphating – A resilient, but abrasive surface is achieved by incorporating a zinc-phosphate layer and corrosion-protective oil.
