Im just finished a hand rail and would like to use some old style coach bolts or something similar. Ive had no luck on the internet yet... Anything from 10 to 12mm.Any ideas . Thanks
They are Coach Bolts (Cup Square Head Bolt) + square nuts (there's no such thing as a 'square head coach bolt') do you mean square head coach/carriage screws (also called Lag screws)??? LIKE THIS
