Frequently Asked Questions

Is there a difference between a lock pin, a retainer pin and a key?

No; they are different industry terms for the same spare part that holds the tool inside the front head.

When should the tool pin (retaining pin) be replaced?

When regular checks reveal excessive wear, deformation or surface damage, it should be replaced immediately to avoid damaging the tool and the front head.

What to watch for when fitting a lock pin?

Make sure the seat is clean before assembly and lubricate the surfaces with suitable grease to reduce friction and wear.

Is the retaining pin under warranty?

No; retaining pins are consumable parts whose service life varies with wear and blank firing, so they are not under warranty unless there is a manufacturing defect.

When will my order be delivered?

In-stock items ship fast; orders within Türkiye are usually delivered within 7 business days. Parts not in stock are produced in below-market lead times.
