Electro Zinc Plated Carbon Steel (ZI) parts are suitable for installation in ductile panels
with a maximum recommended hardness of 80 HRB.
300 Series Stainless Steel (A2) parts are suitable for installation in ductile panels with a
maximum recommended hardness of 70 HRB.
Part number is made up as follows:
(Type)-(Thread)-(Length)-(Material/Finish code)
For example:
NTFH-M3-10-ZI (Thin Panel Stud-M3-10mm long-electro zinc plated carbon steel)
NTFH-M4-12-A2 (Thin Panel Stud-M4-12mm long-stainless steel)
Use part designation NTFHD to specify a dog-point thread lead-in (special order).
Self-Clinching Thin Panel Studs provide strong captivated male threads in panels as thin as 0.51mm. This fastener
does not install fully flush on the underside of the panel.
Utilising a special proven castellated clinch feature, this fastener has good 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.
Reduced Head Studs are available in a range of thread sizes and lengths, manufactured from electro zinc plated
steel, 300 series stainless steel and are suitable for installation in ductile steel and aluminium panels with a
recommended maximum hardness of 80 HRB for steel parts and 70 HRB for 300 series stainless steel parts.
Reduced Head Studs can also be supplied with a dog-point thread lead-in to aid component assembly.
