Danny P Posted December 9, 2017 Share Posted December 9, 2017 Hi, Looking for 6 plow bolts 1/4-20 TPI or 1/4 BSW and 1.5 inches in length as presented in the pictures below. Head diameter is about 16 mm. Who can help me with these or where to find new ones? I found them on the internet as "plow" bolts for agriculture application but the smallest size is M8. No imperial sizes found so far. Regards, Danny Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted December 9, 2017 Share Posted December 9, 2017 Danny, Do a Google search for "countersunk carriage bolts". These are what you are seeking. regards, Richard Quote Link to comment Share on other sites More sharing options...
MB1944 Posted December 9, 2017 Share Posted December 9, 2017 Hi Danny This company lists plough bolts. http://www.gartoninternational.com/news/ They say in their news page that they are sending countersunk bolts to Denmark for a WW11 tank restoration, so they may help you out.

MatchFuzee Posted December 10, 2017 Share Posted December 10, 2017 Imperial but not BSW plough bolts are available here:- http://beeversales.com/products/fasteners/imperial-plough-bolts/ Quote Link to comment Share on other sites More sharing options...
Richard Farrant Posted December 10, 2017 Share Posted December 10, 2017 Danny, you are unlikely to find 'plough' bolts as small as 1/4", The heads are often too small to be used in wood as well, they are meant for use in steel plough shares and points. Look up 'countersunk square bolts' as in the photos in this link. The tend to have a wider head which is better in wood. http://www.fastenerdata.co.uk/fasteners/bolts/more/bolts-a-to-f/countersunk.html Quote Link to comment Share on other sites More sharing options...
brown cow Posted December 19, 2017 Share Posted December 19, 2017 I made up some 1/4 inch using normal coach bolts to use in my Humber heavy utility floorboards. I machined a countersunk hole into some thick plate, the hole large enough to let the square fit. I then heated the head red hot, dropping it quickly into the hole and hammered it into the countersunk hole with a large punch and hammer. After cooling down I lightly machined the head flat. I did about a dozen, they weren't perfect but good enough for floorboards, and they worked ! Afterall you only see the top of the head. The square parts were only damaged slightly if the bolt went in crooked. Easy if you've got all the equipment to hand, and some practice. (sorry no pics to hand) regards Andrew Quote Link to comment Share on other sites More sharing options...
Danny P Posted December 19, 2017 Author Share Posted December 19, 2017 Andrew, that's a great creative idea! Thanks, Danny Quote Link to comment Share on other sites More sharing options...
Bigjohn Posted December 30, 2017 Share Posted December 30, 2017 Are you sure you want "plough bolts"? I have an MW and can't recall seeing a plough bolt on it. There are loads of coach bolts though. Quote Link to comment Share on other sites More sharing options...
Danny P Posted December 31, 2017 Author Share Posted December 31, 2017 Yes, the plow bolts are mentioned in the Bedford authorised service parts book and are listed as bolt, csk, hd. coach, 1/4"-20 x 1 1/2", hoopstick guide plate, qty. 12.
