Triumph Unit 500/350 tappet adjuster set

Triumph Unit 500/350 tappet adjuster setReplace your worn out valve adjusters with this set of English made tappet adjusters. Unlike most on the market today, these are heat treated on the face only, (not induction hardened which leaves the first few threads hardened also). They are copper plated, as the copper plating protects the threads from embrittlement during heat treatment. They have a 2. 5mm allen hex to adjust, and are supplied in sets with nuts.
