Applications & Selection Guide
A2 (AISI 304) hexagon cap (dome) nuts to DIN 1587 — a closed domed top that covers the exposed thread end for safety and a clean finish.
Cap nuts finish railing and balustrade fixings, furniture and display assemblies, machine guards, and any joint where an exposed thread could snag, injure, or corrode. The dome limits how much thread the nut can accept, so check protrusion length before specifying. Metric sizes are listed above.
Sold per piece with a minimum order of 50–100 pieces depending on size. Send sizes, quantities, and delivery country in a quote request.
