MALE
PRESS MOUNT KNURLED STUD General Information: 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. |

Material Notes: Need the strength of a grade 5 or 8 bolt but want it in a stud instead?
Material codes STL4(4140) and STL5(4340) are ideal choices for these options along with grade 4130.
Material codes StSt4(17-4) and StSt2(304) are also options for high tensile strength with the added bonus of being more adverse to rusting. |

Recommended Drill Hole Tolerance: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. 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. |
