Round Head Copper Bolt

• 1.1 Pure copper semi-round head bolts: Mainly made of pure copper, such as T2, T3 and other copper materials, with excellent electrical conductivity, thermal conductivity and corrosion resistance, suitable for occasions with high requirements for electrical conductivity and thermal conductivity and low environmental corrosion.
• 1.2 Copper alloy semi-round head bolts: Common materials include brass (such as H62, H65, etc.) and bronze (such as tin bronze, aluminum bronze, etc.). Brass semi-round head bolts have higher strength and lower prices than pure copper; bronze has better wear resistance, corrosion resistance and other special properties, and can be used in some special working conditions.

2.1 Metric thread semi-round head copper bolts: Using metric thread standards, the thread size is in millimeters, such as M6, M8, M10, etc., which is the most common thread type and is widely used in various mechanical equipment, construction and other fields.

2.2 Imperial threaded copper bolts with round heads: The thread size is in inches, such as 1/4", 3/8", 1/2", etc. They are commonly used in some imported equipment or industries that are in line with international standards, such as aerospace, automobile manufacturing, etc.

3.1 Natural color copper bolts with round heads: They maintain the natural surface state of copper and have the color and texture of copper itself. They are suitable for occasions where the appearance requirements are not high and no additional anti-corrosion treatment is required.

Plated copper bolts with round heads: In order to improve the corrosion resistance, wear resistance or aesthetics of the bolts, the bolts will be plated, such as nickel plating, chrome plating, zinc plating, etc. Nickel-plated copper bolts with round heads have good corrosion resistance and gloss; chrome-plated copper bolts with round heads have high surface hardness and good wear resistance; galvanized copper bolts with round heads have good gloss. It has good anti-rust performance.

1. Selection of transportation mode: According to factors such as transportation distance, transportation volume and urgency of goods, choose the appropriate transportation mode, such as road transportation, railway transportation, air transportation, etc. For short-distance transportation, road transportation is more flexible and convenient; for long-distance and large-scale transportation, the cost of railway transportation is relatively low; for urgent orders, air transportation can ensure fast delivery.

2. Prevent corrosion: If you may encounter damp, bad weather or corrosive environment during transportation, take corresponding protective measures, such as covering with waterproof canvas, placing desiccant in the package, etc., to prevent the bolts from rusting and corrosion.
