The Finer Details Uprated Frankenstein Bolts for Mazda MX-5 NA NB

Beautifully made by The Finer Details, these uprated Frankenstein bolts are a direct replacement to the OEM bolts. Both designed and manufactured in the UK, the bolts are handmade from a single piece of aircraft-grade stainless steel with the mirror finish being hand-polished.

Instead of a cross head screw, which can easily be gouged, a 16mm spanner is used to tighten them onto the car. This has an added security benefit, as most standard car toolboxes do not have a 16mm spanner.


  • Handmade in the UK
  • Available in both raw and mirror finish
  • Sold as a pair
  • Made out of aircraft-grade stainless steel
Weight N/A
Dimensions 8 × 6 × 3 cm

    I purchased these directly from the seller via Facebook whilst they were still in the first batch released to the public for testing. I have to say the quality is amazing and I would go as far as saying they are much better than the original Mazda ones due to them having two machined flats on them so they can be easily removed rather than rounding them with a Philips head screwdriver. A great product and a must for anyone running a hardtop.
