Self-clinching nut
Our SELF-CLINCHING NUT is a threaded insert with a knurled collar and clinching groove. When inserted in the sheet metal, the knurled collar allows for the sheet metal to slide uniformly into the fastener’s clinching groove to ensure a tight, secure fit.
Technical data
BENEFITS
- High torque-out resistance.
- The insert remains fully flush on the opposite side of the sheet metal.
- Its reduced size makes this type of insert ideal for all electronics and other precision equipment.
- Easy to install with any type of squeeze-action press.
DESIGN GUIDE
PREPARING THE HOLE
Holes may be punched or drilled, so long as they remain within a tolerance range of -0.00/+0.08 mm.
SHEET METAL HARDNESS
Must be less than 80 RB (150 HV) for steel fasteners and less than 70 RB (128 HV) for stainless-steel fasteners.
ASSEMBLY
Gradual pressure must always be used to install these inserts. NEVER apply aggressive forces with a mechanical press. A hydraulic press should be used instead.
CLAMPABLE THICKNESS OF SHEET METAL
Self-clinching fasteners are suited to any thickness of material down to a minimum of 0.8 mm (M2-M5). For other threading, see the table.
SHANK LENGTH
Always select the longest shank possible for the thickness of the sheet metal. This optimizes resistance to pull-out and lateral forces.
DIRECTION OF USE
We recommend that self-clinching fasteners always be used from the side opposite the head of the insert.
STANDARD MATERIAL
Heat-treated steel, to be used with materials softer than 80 RB (150 HV) (types PS and PSI). Austenitic stainless steel (18/8) (types PSS and PSIS). Stainless steel series 400 for AISI 304 sheet metal.
STANDARD FINISH
Zinc plating and Clear passivation.
AVAILABLE UPON REQUEST
