What size wrench you need to run one of these down, is it a standard hex head that'll fit regular shop tools?

Question by: Ray J on Aug 10, 2025, 4:24 PM

Hex head cap screws in the 5/8-11 thread family take a 15/16 inch wrench or socket, which is a standard size you'll find in just about any shop set. No specialty tooling needed for installation or removal.

got a Permco pump on the bench. is this the right bolt if i need a 5/8-11 thread and 3-1/2 inch long?

Question by: Denise R on Oct 7, 2025, 3:04 PM

Match the basics: this Permco cap screw is 5/8-11 thread and 3-1/2 inches long, with a hex head. If those are the dimensions you pulled off the old fastener, it is the correct size to replace it.
