"Hide the hardware. Keep the character."

The Undercover Screw Concealer — 22mm Square Head with Threaded Rod is the most secure screw concealment solution on the market. Unlike press-fit caps that pop off or adhesive stickers that peel, this patent-pending two-piece design threads directly over your existing screw head — locking the concealer permanently in place while delivering bold, vintage square-head carriage bolt aesthetics.

The threaded rod insert screws into the base, capturing the fastener beneath and creating a rock-solid finished detail that won't budge — even in high-traffic or exterior applications.
