Electro Zinc Plated Steel (ZI) parts are suitable for installation in ductile panels with a
maximum recommended hardness of 60 HRB.
300 Series Stainless Steel (A2) parts are suitable for installation in ductile panels with a
maximum recommended hardness of 70 HRB.
400 Series Stainless Steel (400) parts are suitable for installation in ductile panels with a
maximum recommended hardness of 88 HRB.
Aluminium (AL) parts are suitable for installation in ductile panels with a maximum
recommended hardness of 50 HRB.
Part number is made up as follows:
(Type)-(Thread Code)-(Length)-(Material/Finish Code)
For example:
NTSO-M3-10-A2 (Thin panel standoff-M3 thread-10mm long-stainless steel)
NTSO-5.4M2.5-4-AL(Thin panel standoff-M2.5thread (larger body)-4mm long-aluminium)
NTSO-M3.5-8-ZI (Thin panel standoff-M3.5 thread-8mm long-electro zinc plated steel)
Self-Clinching Thin Panel Standoffs provide strong captivated reusable female threads in a spacer format in panels
as thin as 0.63mm.
Utilising a hexagon head and a special proven clinch feature, this fastener has excellent torque-out, pull-through
and push-out characteristics whilst providing a flush finish on the underside of the panel, meaning that minimal
surface finishing is required after installation.
Like all self clinching fasteners they are installed using a parallel squeezing action, so require access to both sides of
the panel.
Self-Clinching Thin Panel Standoffs are available in a range of thread sizes and lengths, manufactured from electro
zinc plated carbon steel, 300 and 400 series stainless steel, aluminium and are suitable for installation in ductile
panels with a recommended maximum hardness of 60 HRB for steel parts, 70 HRB for 300 series stainless steel
parts, 88 HRB for 400 series stainless steel parts and 50 HRB for aluminium parts.
