M3 Hex Cap Nut Class 6 Bright Zinc Plated (DIN 1587)

Hex Cap Nut Class 6 Bright Zinc Plated (DIN 1587)

A hex cap nut, often called a domed or acorn nut, adds a clean finish to threaded connections by enclosing the exposed end of the bolt or stud. Its closed end protects threads and shields users from sharp edges, making it ideal for decorative or safety-critical applications. The hex shape allows easy tightening and removal with standard wrenches, while the domed cap ensures no snagging on fabrics or equipment.

Made from property class 6 steel and finished with a bright zinc coating, this nut offers moderate strength and basic corrosion resistance. Cap nuts are commonly used wherever a neat appearance and protection are required such as on furniture, machinery, vehicles, fitness equipment or exposed threaded rods. Select the matching size to your bolt for a secure, durable and visually appealing fastening.
