Caliper, 6" Inside Spring

Picked this up for measuring the inner diameter of some pipe fittings, and the spring-loaded action holds the setting perfectly when I transfer it to my rule. The 6-inch reach is just right for the sort of engine work I was doing.

Needed to check the bore on a cylinder head and this caliper transferred the measurement to my rule perfectly. The 6-inch reach handled it easily, and the spring tension held the setting without slipping.

I’ve used it to check the bore on a couple of machine parts, and the 6-inch reach lets me get deep inside without any guesswork. The spring tension feels just right—firm enough to hold the setting solidly, but not so stiff that it’s a fight to adjust. Works as advertised for transferring measurement
