From another thread asking a similar question about grub screws from HP TE, this subject is a common topic on many forums, vintage TE from most US makers use the same sizes, some use Bristol spline instead of hex/Allen screws. --- Quote from: factory on June 10, 2024, 06:40:15 pm ---It shouldn't be hard to find grub screws in UNC sizes where you are, you have places such as McMaster-Carr; https://www.mcmaster.com/products/screws/fastener-head-type~headless/set-screws~/thread-type~unc/ In the UK I've used Accu, choice isn't as good of course; https://www.accu.co.uk/shop/precision-components/precision-screws/grub-screws/socket-head-set-screws/imperial-cup-point-setgrub-screws?page=1 The common sizes of grub screw & allen keys used for HP TE, the #8-32 is usually found on much older HP TE; #8-32, 5/64" #6-32, 1/16" #4-40, 0.05" (50 thou) #2-56, 0.035" (35 thou) For removing the grub screws I usually tighten them first to break the corrosion, it works for me most of the time, if it's too far gone drilling is probably the only option. Tek stuff seems worse with steel grub screws into aluminium. David --- End quote --- David |
