Bolt is a hard thorn object, one end has a hat: in riveting, by its own deformation or transition with the riveting part. There are many kinds of bolts and they are informal. The common ones are r-bolt, cooling fan bolt, blind bolt (core bolt), tree bolt, semicircular head, small flat head, half space center bolt, solid core bolt, low head bolt, blind bolt, hollow bolt. The self deformation connection is riveted. Cold bolts, generally less than 8mm, are larger hot bolts. Bolt manufacturer

Common types of bolts are: r-bolt, cooling fan bolt, core bolt, tree bolt, semicircular head, small flat head, half space center bolt, solid core bolt, low head bolt, blind bolt, hollow bolt, etc.

1、 R-type plastic bolt: also known as expansion bolt, it consists of two parts: plastic nail and female buckle. All special tools are not needed for the installation of color rivets. Just place the mounting base in a clean hole and hold the top of the head down. The support legs of the unique design scheme are then inflated and firmly locked on the surface to be installed.

2、 Cooling fan bolt: excellent ductility, designed for manual installation, can be pulled out according to the hole of control panel or car chassis. The key of cooling fan bolt is to fix electronic products, computer chassis fan, heat pipe radiator and integrated IC, which has the function of shock proof and noise reduction.

3、 Core bolt: riveting is very convenient. Two sides of double drum rivets or some parts of several connections can be riveted according to one side pounding the core.

According to the appearance of nut cap, core bolt can be divided into flat core bolt and low head core bolt.

According to different raw material composition, it can be divided into aluminum core bolt, aluminum steel core bolt, all stainless steel plate core bolt, steel core bolt, aluminum stainless steel plate core bolt, plastic core bolt, etc.

1、 Plastic tree bolt: also known as inverted tooth plastic bolt, Christmas decoration plastic bolt, plastic tree bolt with high-quality dielectric strength, fire safety characteristics, no magnetic, thermal insulation, light weight, heat resistance, high compressive strength, good corrosion resistance, widely used in various industrial production industries.

2、 Countersunk blind bolt: after riveting, the riveting position is riveted, and the surface is smooth and beautiful.

3、 Double drum type blind bolt: when riveting, the rivet core will pull the top of the bolt body into a double pair of drums. The double drum countersunk head rivet and clamp the two parts to be riveted, so as to reduce the working pressure on the surface of the parts.

4、 Large and medium cap bolts: compared with common blind bolts, the diameter of the aluminum cover is significantly enlarged, the total area of the bolt and the connecting parts are riveted, and the support point surface is stronger, which improves the torque compressive strength and undertakes higher axial tension.

5、 Closed trial blind bolt: the design scheme is used for riveting the rear encapsulated spindle head, which has the characteristics of high shear, vibration resistance and high pressure resistance.

6、 Aluminum blind bolt: the bolt body is made of high quality aluminum wire. After riveting, it is beautiful, durable and corrosion-free, but the riveting compressive strength of bolts is low, which is suitable for RF connectors with too soft raw materials.

7、 Open mouth stainless steel rivet: this kind of bolt is a good choice for high compressive strength and corrosion resistance.
