These are solid brass and chrome plated. The H bolt hold down bolts are just the thing if you are into period old school speed equipment.
They suit aftermarket Holden grey motor alloy rocker covers.
These rocker cover bolts are hand moulded sand cast brass that are machined, drilled, tapped then hand polished.
They are chromed plated just like the original.
Be sure to check out the rest of the Aussiespeed® range of early Holden speed and dress up equipment with items like dual cast iron finned exhaust headers, aluminium rocker covers, aluminium sideplates and down draft Stromburg air cleaners.
