Part Number Examples
Part number is made up as follows:
(Type)-(Thread)-(Length)-(Material/Finish code)
For example:
NHFE-M6-20-ZI (Heavy Duty Stud-M6-20mm long-electro zinc plated through-hardened
steel)
Use part designation NHTSD to specify a dog-point thread lead-in (special order).
Info
Self-Clinching Thin Panel High Strength Studs provide high strength captivated male threads in panels as thin as
1.0mm. This fastener does not install fully flush on the underside of the panel.
Utilising a special proven castellated clinch feature and a larger diameter head, this fastener has very high torque-
out, pull-through and push-out characteristics whilst providing minimal protrusion on the underside of the panel
(refer to S dimension).
Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of
the panel.
Thin Panel High Strength Studs are available in a range of thread sizes and lengths, manufactured from electro zinc
plated through-hardened steel, 300 series stainless steel and are suitable for installation in ductile panels with a
recommended maximum hardness of 85 HRB for steel parts and 70 HRB for 300 series stainless steel parts.
Thin Panel High Strength Studs can also be supplied with a dog-point thread lead-in to aid component assembly.
