Concealed-Head Studs CHC, CHA, CFHC, CFHA

SKU: CHC, CHA, CFHC, CFHA
PEM® self-clinching concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as 1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications. Their concealed-head feature contributes particular design benefits by allowing the side of the sheet opposite installation to remain smooth and untouched. This feature additionally serves to satisfy applications where the sheet must remain completely sealed from air, liquid, dust, gases, or other potentially infiltrating elements.

Product Details
PEM® self-clinching concealed-head studs and standoffs install permanently in steel or aluminum sheets as thin as 1.6mm to provide strong and reusable threads for mating hardware in a wide range of thin-metal assembly applications.  Their concealed-head feature contributes particular design benefits by allowing the side of the sheet opposite installation to remain smooth and untouched.  This feature additionally serves to satisfy applications where the sheet must remain completely sealed from air, liquid, dust, gases, or other potentially infiltrating elements.
 
            The aluminum or stainless steel studs are available in thread sizes #4-40 through #10-32 and M3 through M5 and in lengths from .250" through 1" and 6mm through 25mm.  Stainless steel standoffs are offered in thread sizes #4-40 through 1/4-20 and M3 through M6 and in lengths from .187" through 1" and 4mm through 25mm.
 
            Sheet preparation for their installation requires only a blind milled hole to the recommended minimum depth.  Using a PEMSERTER® or other standard press, installation is accomplished by placing the fastener in the hole and applying sufficient squeezing force.  The fastener head then locks securely in the sheet and can handle substantial loads.
 
These fasteners are RoHS-compliant and some stud types meet NASM63540 specifications.
