Characteristics and applications of carriage bolts

The carriage bolts is a type of fastener composed of two parts: head and screw(cylindrical body with an external thread).It needs to be matched with the nut to fasten the two parts with pores with pores.


The carriage bolts are divided into large round head carbone bolts according to the head size(corresponding standard GB/T14 and DIN603),and small round-headed carriage bolts (corresponding standard GB/T12-85).


The carriage bolts is used in the slot.The square neck is stuck in the slot during the installation process. It can prevent the bolt from rotating.The carriage bolts can move parallel in the groove. Because the head of the carriage bolts is round,there is no design of the available help tools such as cross grooves or inner hexagonal,and it can also play a role in anti -theft in the actual connection process.


The main materials of carriage bolts include carbon steel,steel, stainless steel.


The surface treatment methods of carriage bolts are galvanized, chrome,copper plating,and blackened surface.


The process is controlled layer by layer, and everyone pays attention to quality.


(1) Quality:Products use high-quality materials to ensure quality. We have a professional QC team to inspect every project from production to packaging.And before leaving the factory,all specifications of products are sampled and tested to ensure stable quality.We guarantee the high-quality coating and low roughness of bolts.


(2) Product features:Straight,not easy to break,sharp thread, good drill-ability.


(3) Strict quality control:For each order,the quality control department will conduct strict inspection before delivery.Poor quality will be avoided in the door.


(4) Transportation:We have transportation department and freight forwarder,so we can ensure faster delivery and better protection of goods.


(5) Efficiency:Fast production time,only 260 minutes away from the nearest Shanghai port.


(6) Service:Customer service answers customer questions online 24 hours a day,and uses high-quality materials to ensure quality.


PS:Before shipment,we will sample the bolts of each specification for basic test.

The basic test items we do:hardness test,yield ratio,torque value,anti slip coefficient,tensile strength,nondestructive testing,stress test,thread test,size test,preload test.If you have requirements,you can also carry out salt spray test and fault analysis.Let you buy at ease and use at ease.

Instructions for the use of carriage bolts

1. During installation,the carriage bolts shall be freely penetrated into the hole and shall not be knocked by force.


2. When the carriage bolts cannot be threaded freely,it is not allowed to use gas cutting to enlarge the hole.Instead,it is required to use a reamer to make the hole.When repairing the hole,the plate layer should be closely attached to prevent iron filings from entering the plate seam.After the hole is reamed,a grinder should be used to remove the burr on the hole edge and iron filings.


3. The carriage bolts should be threaded in the same direction, and then tightened with a wrench.The carriage bolts shall not be installed in rainy days, and the friction surface shall be dry.


Packing method of carriage bolts

We usually use bulk,color box,kraft carton,PC plastic box,PC plastic bucket,tray and other packaging methods.

Of course,customers can also customize.
