When covering an enlarged, elongated or irregular hole, centre the washer so its full bearing face sits over sound material on both sides of the hole before tightening down - this spreads the clamping load evenly across the wide diameter rather than concentrating it at one edge, which is the whole point of fitting a penny washer in place of a standard one. On a bodywork repair, check the washer fully bridges the damaged area on the outer face before you tighten the fixing down, since it's this outer coverage that stops the joint working loose again through the enlarged hole.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCommon Questions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhich size do I need?\u003c\/strong\u003e\u003cbr\u003eMatch the inner diameter (d1) to your bolt or screw: for example, an M5 washer has a 5.3mm (0.21in) hole for an M5 fixing.
