Carriage bolt

  The 45 degree angle at the neck of American standard carriage bolt has been a technical problem in the mainland, with high cost, low efficiency, unstable quality, and high risk. So many factories tend to produce American standard carriage bolt with seaming on the neck. EF pursues to provide customers with high-end fasteners of high quality at reasonable price; therefore, EF has been committed to the development of 45 degree angle square neck American standard carriage bolt. After one year of development, cost and quality control, EF has been able to produce qualified 45 degree angle carriage bolt with good appearance, and reasonable price.
