Source and size of Spitfire Frame 5 spar bolts

Oh well, here goes I hope to bolt the carry through wing spars to the firewall soon….hence I need some bolts, the 1/4 inch ones that hold the carry thru spars to the firewall/Frame 5 (not the wing bolts that attach the wing spar to firewall carry thru spars….does anyone know the size and a source? It is a static so someone with some originals would be even nice….fingers and everything crossed!!!

Hi Rocketeer, I measured those bolts as promised and as Chumpy said they are A25-41E’s. good luck !!

cheers Stu

Theres a chap selling NOS bolts on ebay, he’s in Norfolk I think (no not him!); I got mine from him, he does high tensile and mild, and they are very reasonable.

The long ones I think are A25-41E’s, rare as rocking horse s**te. Just had a look on the LAS website..£9.95 EACH… luckily they have none in stock!

For a static better off using commercial 6mm bolts, bit slack in the holes..but way way cheaper.

Many thanx Steve…yep those are the ones

Sorry, that will teach me for not being specific!! I did not mean those (wing)bolts (and yes I did know about oversize etc, non-interchangeability and the fire wall plates)…..I meant the bolts that go through the spars, spacer castings and the firewall/fr5:)

Hi Rocketeer,I guess you mean the 1/4 dia bolts that hold the carry through spars to fr5 ? When i go to work tomorrow i’ll measure the length for you. If you want the real thing then they are A25,s but a cheaper option would be A102,s which are a unified thread. Companys like LAS aero spares could help you ! or alternativly as its a static try your local hardware shop !
