HIGH TENSILE STUDS
INTEGRAL STUDS
Steel studs are available in the CMHD/CFHD, HM/HF,
HM-C/HF-C and KF Series to facilitate right angle
connections. Standard misalignment is 50° in all sizes.
Threads are only available as right hand. There are two
types of studs available:
High Tensile Steel Studs–(Y Suffix)
High tensile steel studs are available for sizes 3 through
12. These studs are machined for exact fit-up within
the ball bore, providing smooth operation and high
performance. The studs are assembled to maintain the
internal clearances inherent in the Rod Ends. They are
permanently secured in the bore of the ball, threaded for
easy mounting and have a hex section to facilitate
tightening. The stud is designed to accommodate 50°
misalignment in any direction, and provides maximum
load capacity.
Integral Ball Studs–(S Suffix)
The ball and stud are combined into a single unit of
case hardened machined plated steel. Wrench flats
are provided for tightening. These studs offer the same
operational features as the high tensile studs, with
slightly reduced load capacity. The integral studs are
available in sizes 3 through 8 only.
