*Recommended diameter tolerance of stud for PH
and PZ fasteners is ±.005"; for PA fasteners, +.002"
and -.003". Surface hardness of stud must not
exceed Rockwell 30T-78. Nickel-chrome plating on
studs for PH fasteners must not exceed .001".
Nickel-chrome plating or other hard finishes not
recommended on steel studs for PA fasteners.
Arched types provide spring tension or “takeup”
to compensate for unavoidable slack.
Round styles require minimum space. These
styles develop optimum clamping strength only
when the body arch is substantially flattened
against the work. Therefore, the bearing surface
must be hard enough for the fastener edge to
slide on, strong enough to resist breaking, and
rigid enough not to yield.
