(1)What are flat washers for?
Flat washers prevent sinking of bearing surfaces,The main role of flat washers is to increase the size of a screw’s bearing surface area, and reduce the surface pressure applied on the fastened object.
(2)What is the difference between a flat washer and a fender washer?
A fender washer, though similar in shape to a standard washer, differs in that the outside diameter is traditionally much larger in proportion to the center hole. With this design, a fender washer can be placed under the head of a bolt or nut to help distribute forces applied when tightening.
(3)Do I need a flat washer with a lock washer?
Flat washers are used to increase the surface area in order to more evenly distribute the force applied with tightening the fastener. Lock washers are used as a means of creating tension during tightening in order to help keep the nut from working loose later.
(4)What goes first lock washer or flat washer?
When used correctly, a lock washer will hold the nut or other threaded fastener in place. To help it accomplish this, put the lock washer on first, below the fastener. If your project calls for other washers or hardware elements, they should go on before the lock washer so that it can hold them in place.Our target should be to consolidate and improve the high-quality and repair of current goods, in the meantime regularly produce new solutions to meet unique customers’ needs for Wholesale Price China Carbon Steel, Stainless Steel, Metal Galvanized Flat Gasket, Ultra-Thin Gasket, Screw Washer, Galvanized, Hot Galvanized, We feel you are going to be happy with our affordable selling price, top quality solutions and rapidly delivery.
