Boltright / M6 Resto Kits

M6 resto kits

A box of the M6 hardware an old Japanese car is held together with, sorted into labelled bags. Not tied to one car, so it suits any restoration where the M6 bolts are past saving.

Variety or core

The variety kit has the widest spread: SEMS screws in every common length, 4 mark and 7 mark bolts, flange bolts, every type of nut and washer, and the odd ones you only notice when one is missing, like wing nuts, weld nuts and tooth washers. The core kit has fewer types in bigger numbers, for the bolts a car uses most.

JIS small head, factory finishes

Every bolt is M6 × 1.0 with a Japanese small head, so it takes a 10 mm spanner like the originals. The 4 and 7 marks are stamped on the heads where the factory used them. Yellow zinc and blue zinc kits are made to match the plating on the car. A few items are not made in blue zinc, so the blue variety kit has some bags in trivalent white zinc, and both variety kits include tooth washers in trivalent white. Each one is marked on the kit page.

Other sizes

M8 Resto Kits with 12 mm JIS heads are coming soon in the same four versions, along with M10, M5, M4 and smaller, and a self-tapping screw kit. An M12 kit is being considered.
