I have a powerfix (LIDL) reciprocal saw that I bought over 10 years ago. With the opening and closing of the bolt (to change the saw blade) it eventually burred and I thought that was the end of the saw. I removed the bolt and took the measurements, went onto desertcart and lo and behold they were for sale. The ones I bought were marginally longer than I expected but this was my fault as the measurements I was looking for did include the bolt head whereas the manufacturer did not include the bolt head. This meant it was about 5 mm longer than expected. Remember this when ordering. Anyway they worked wonderfully and the fact that I have a few of them as spares will mean they will surely outlast the saw. But who knows? Review: Very quick and easy install. - Arrived on time, minimal packing and item as described and fits perfectly. Very quick and easy install.
