CSS/CSOS Concealed-Head Standoffs

PEM CSS/CSOS Concealed-Head Standoffs ensure permanent mounting in metal sheets as thin as 0.062". These standoffs feature a fastener head that is locked securely in a blind milled hole and is built to withstand substantial loads. The concealed-head feature allows the side of the sheet opposite installation to remain smooth, ensuring secure placement without gaps or breaks. Little sheet preparation is required with these standoffs. Users can mill a blind hole to the recommended minimum depth, install the concealed-head standoffs using a hollow anvil and solid punch, place the head of the fastener in the hole, and insert using any standard press. PEM CSS/CSOS Stainless Steel Standoffs are suitable for various markets, including automotive, datacom, electric vehicles, medical, and industrial.
