PTP has added Size-On-Size Studs – AS3319/AS3320/AS3321/AS3322 – to its product portfolio, in alloy steel, A286 steels, Inconel and titanium.

Size-on-size studs are similar to ring locked studs, except that threads have a common nominal diameter that allows the stud to be installed into minimum size bosses. The captivated lock-ring provides a positive lock against rotation, transferring high torque loads from the stud to the base material while the stud threads resist tension loads. Available sizes are 0.164 to 0.375 and 5mm to 12mm.
