Stud
Threaded stud (Stud with thread)
MPL (Millimeter Partial stud) /
ACSMP (ACS Millimeter Partial stud)
- Most popular partial threaded stud
- Strength of joint = Tension strength of thread
- Welding diameter = Rolling diameter for thread
- Please designate thread size, common length and thread length when you place the order.

MFL (Millimeter Full thread stud)
- Full thread stud except collar part
- Strength of joint = Tension strength of thread
- In principle, zinc plating is not available.
(Because removal of zinc plating from tip of stud is necessary, this stud will be partial threaded stud like MPL.) - Please designate thread size, common length and thread length when you place the order.
