Bronze or gunmetal screws/bolts

 1607 forum posts 69 photos | Reading up on boiler construction it is suggested that small bronze or gunmetal bolts can be used to hold parts together for brazing, but on no account to use brass as such screws would melt away at silver soldering temperatures. Has anyone any suggestions as to where these can be purchased in small sizes?? Metric, imperial or ba immaterial as a taps to suit are probably easier to find that the screws themselves! |
