Standard flat washers do not present a proper bearing surface when used to bolt tubing joints. This can result in damage to the washer or to the tubing, which eventually allows the bolt to loosen. The result is excessive free play, vague shifter feel, and missed shifts. Our plated steel saddle washers are profiled to be a precise fit on the OD of Apex and Borgeson shift linkage joints, but they can be used on any bolted tube assembly with the same outside diameter. All sizes accept a 1/4" bolt (0.250") with a 1/2" OD to match standard AN960-416 washers. Each washer adds 0.093" to the required grip length. Sold individually.
