MALE PRESS MOUNT KNURLED STUD
HEX OR ROUND
Male press mounted knurled studs, also known as ground studs, can be a better alternative to the use of standard bolts. The low profile head can allow the studs to be mounted closer to the surface, resulting in a more efficent mounting process. It can be a completely flush mounted stud by either eliminating the collar or by counterboring the hole the stud is being mounted in providing the board/plate is thick enough to allow this.
Like all of our products, these studs can be modified to fit the needs of the individual customer. Modifications to thread length (B=.515), thread type (M12 X 1.75 instead of M12 X 1.5), collar length (Collar = .075), and knurl length (C=.130) are possible modifications.
Not all materials are offered in Hex. Please contact us to find out which grades are available.
Need the strength of 10.9 bolt but want it in a stud instead? Choose material code STL4(4140)and it can be heat treated to the optimum requirements needed.
Note: The material mentioned above is offered as a suggestion only. Engineering tests should be used to determine if the product meets form and function desired.

Recommended Drill Hole Tolerances:
For the best installation results, try to keep the hole the stud is going to be installed into as close to the hole size mentioned above. Generally speaking, keeping it to a +.002/-.000 is the ideal condition for these parts to install properly. I fthe hole size is too large, the stud will not hold properly with the possiblity of pushing out. If the hole is too small, the stud or the board/plate may break. To add better retention in a board/plate, these items could be welded or soldered providing that the items are properly prepared and that it will not affect any fuction of the assembly.
