Repair vs Replace Screw

Should my worn screw be repaired or replaced?

Obviously, there are many factors that can influence this decision. Due to the various types of wear, it is best to have your screw manufacturer evaluate the screw and help guide you in making a decision that is right for you. Generally, the size of the screw, the amount of wear on the root of the screw, and the design of the screw are the three most common determining factors influencing your decision to rebuild any screw.

“If the design of the worn screw matches your processing needs and the root is not worn enough to alter that design, rebuild it.”

One exception to the rule stated above is that smaller screws (under 50mm or 2”) generally cost as much to rebuild as a new tool steel replacement screw, from which you will receive increased wear resistance. This is when a quality rebuilder can help guide you in making a decision.

A properly rebuilt and polished screw can be as effective as a new one and an economical alternative to a new screw purchase.
