HANDLE BAR PINCH BOLT UK (UNF THREAD)

This is the pinch bolt that clamps the handlebar mounting on the top of the fork, used on the UK-spec fork clamps with UNF threading. It shows up across a long run of catalog entries covering telescopic front fork and handlebar mounting figures, including the T100C/T100R and TR6C USA-fork listings, so it's a part that saw duty on a wide range of fork and handlebar setups over the years.
