Product Description

Electro - galvanized cap nuts, also known as nut caps, are a type of fastener with multiple functions

Basic Structure

Material and Coating

Functions

Cap nuts are usually dome - shaped, and specifically, they are often domed hex nuts. They can be regarded as standard hex nuts with a closed end, which can cover the end of the bolt, protecting the bolt threads and preventing external damage.

They are typically made of mild steel and then undergo electro - galvanizing treatment. The electro - galvanizing process coats a layer of zinc on the surface of the cap nuts, which can provide good corrosion resistance.

Firstly, they can protect the bolt threads from damage, such as preventing threads from being scratched, deformed or corroded by external objects. Secondly, they can cover the sharp edges of the bolts, reducing the risk of accidental scratches or injuries, and providing a safer working and using environment.

Packing & Delivery

Plastic Bags

Cartons

Each batch of electro - galvanized cap nuts with the same specification is first packed in polyethylene plastic bags. The thickness of the plastic bags is generally 0.03 - 0.05mm, which has good moisture - proof and dust - proof effects. The plastic bags are sealed tightly by heat sealing to prevent the cap nuts from falling out and to isolate external moisture and dust. For example, 100 pieces of M8 electro - galvanized cap nuts are put into a plastic bag, and the bag is sealed after exhausting the air as much as possible.

The plastic - bagged electro - galvanized cap nuts are packed into corrugated cartons. The cartons are made of high - strength corrugated paper, with a thickness of 3 - 5mm, which has good pressure resistance and shock absorption. The size of the carton is determined according to the quantity and specification of the cap nuts. For example, a carton for M10 electro - galvanized cap nuts can hold 50 plastic bags (each containing 50 nuts), and its dimensions are about 30cm × 20cm × 15cm. A layer of moisture - proof paper is laid at the bottom and top of the carton to prevent moisture from entering from the outside.
