U-bolts production process galvanized U-bolt fastener manufacturer Yuanlong

Product Name: U-bolts Alias: horse bolts, U-Bolt, U-bolt, U-shaped hook member, U type wire, U-bolt thread tolerance: 6g production standards: in strict accordance with JB / ZQ4321-1997 state standards. Product Grade: 4.8 6.8 8.8 10.9 Finish: black, yellow zinc plated, white zinc plated, hot dip galvanized, hot infiltration of zinc plating Dacromet practical purposes: mainly for fixing the tubular pipe or sheet such as automobile The leaf spring construction and installation, machinery parts connected, vehicles, ships, bridges, tunnels and railways. Main shape: semicircular, square rectangular, triangular, oblique triangle. Material: Stainless steel Q235A Q345B steel manufacturing process: process outlined as follows: The material testing roller tip --- --- --- pickling peel off --- --- --- then pull down angle rolling thread --- --- --- thermoformed plastic product advantages: a stable quality, complete specifications, adequate goods, low prices, convenient delivery Features: 1, high efficiency, with significant energy savings. 2, the heating temperature is high, time is short, which means that the heating speed (high efficiency, high yield per unit time) 3, easy to implement automatic control (to improve product quality and pass rate) 4 ,? improve and protect the environment (air environment to protect the health of the operator to ensure) 5, safe (no fire, to prevent fire, greatly improved safety performance) 6, easy operation (no warm-up and shut down at any time, while saving energy) 7, the installation space occupied small area (an area of ??only two square meters, saving space and capital costs) 8 ,? the workpiece can be local heating, 24-hour work Caution: (1) surface rust, oil, bolt burr hole wall, welding tumor, etc. should be clean. (2) contact friction surface treated to achieve the required anti-zoned shift factor requirements. We should be supporting the use of high strength bolts nuts, washers, when used according to package, and may not be interchanged. (3) Handled member friction surface installations do not allow stick oil, dirt and other debris. (4) when you install the friction surfaces should be kept dry and should not work in the rain. (5) strict check and correct the deformation of steel connections before installation. (6) prohibits Driven bolt threaded bolt to prevent damage during installation. (7) the use of periodic testing of electric wrench, ensure the accuracy of torque, in the correct order tightening operation. Safety measures: Use the wrench spanner mouth size should match the size of the nut should not be used on a small wrench cased. High altitude operations should use a wrench to die with a rope tied firmly as with wrenches, the people to wear seatbelts. Steel components assembled connecting bolt, do not touch the surface of the plug connector or Tanmo screw, to take place when the horn plate, the finger should be placed on both sides of the horn plate. U-bolts although there is a small part but really big role. Choose the time to choose a good quality, used to pay attention to treating the surface of rust or oil, to keep dry handle the future, do not stick debris to ensure proper operation, the connections are tight after-sales service: The company holds quality the price, in order to conquer the concept of customer service and new and old customers so the company's products, such as the (ten days can be swapped with any questions.) Shipping way: logistics, container, direct delivery, etc. Note: The company is in the production of fasteners collectively have access to the country's daily logistics distribution vehicle enabling easy delivery, receiving timely.
