Hi Mr Underhill,

We were opposite you at the Spring meet in a Troll.
I just bought some 11mm herzim from Jandi @ .50p/m as mine was coming adrift in the hot weather. As soon as I pulled it away I discovered that a lot of my screws were degraded, after copious digging on line I found a company called Cromwell who do the flat head phillips in the two sizes , needed.
If I have ordered the correct ones I will advise you >

Mike.


degraded and needed replacing, eventually

Regarding the pop top bolts just gone the same way myself replaced with stainless 30mm x M6 with the 3/4 inch tap washer. Then on top of the tap washer 1 inch M6 stainless steel washer to completely cover the rubber tap washer. Tightened with stainless nut underneath then finger tight second stainless nut just for locking purposes. A bit of waterproof grease on threads and filled the hexagon top on the mushroom bolts just for good measure job done!
