HEX CAP NUT DIN-917

📌 Overview

The Stainless Steel Hex Cap Nut DIN 917 is a hexagonal nut with a low, domed closed end, designed to cover and protect the exposed screw or bolt threads. Unlike standard dome nuts (DIN 1587), DIN 917 cap nuts feature a lower profile, making them ideal for applications where a compact, protective, and aesthetic finish is required.

Made from SS304 (A2) and SS316 (A4) stainless steel, these nuts provide excellent corrosion resistance, durability, and strength, making them suitable for automotive, furniture, architectural, marine, and machinery applications.
