joinathanbrooks Posted November 8, 2018 Report Share Posted November 8, 2018 I have a lot of paint in the welded on nut that this screw goes into. Does anybody know the thread type, size, pitch as I would like to buy a tap to clean the threads up? Quote Link to post Share on other sites
RogerH Posted November 8, 2018 Report Share Posted November 8, 2018 Hi, this is the Moss P/No. SH604121 SH - screw hexhead 6 = UNF 4 = 1/4 dia 12 = 1 1/2 (12 x 1/8") 1 = Nickle finish or whatever. Roger Quote Link to post Share on other sites
joinathanbrooks Posted November 8, 2018 Author Report Share Posted November 8, 2018 Thanks Roger although that is item number 37 in the attached parts list. Item 37 passes through item 36, which is used to adjust the height. Item 36 (on attached) is item 35 on moss https://www.moss-europe.co.uk/screw-adjusting-626157.html?assoc=131376. It3m 36 (on attached) is the darker item in the attached picture. I need a tap for the green nut in the picture. Quote Link to post Share on other sites
RogerH Posted November 8, 2018 Report Share Posted November 8, 2018 Hi, no problem. it will be UNF. Measure the OD of the thread and round to the nearest sensible fraction - 5/16, 3/8. 7/16. Roger Quote Link to post Share on other sites
joinathanbrooks Posted November 10, 2018 Author Report Share Posted November 10, 2018 I can confirm that it is 1/2" UNF 20 Quote Link to post Share on other sites
