DIN 931 Partially Threaded Hex Cap Screw

Product details

Bolts are generally composed of a driving head and a threaded rod, and the threaded rod is machined with full threads, half threads, etc. as required. At present, the driving head of the prior art is usually set as a cylindrical driving head, but the friction force of the round head driving head is insufficient. During the tightening process, the wrench is easy to slip on the driving head, causing misoperation and increasing the difficulty of tightening. .

In view of the problem that the bolts are easy to slip during the fixing operation and cause misoperation, a hexagonal half-threaded bolt is provided, which includes a hexagonal bolt head and a threaded shaft. The threaded shaft includes a smooth shaft and a threaded portion. The smooth shaft The length is 40% 60% of the total length of the threaded rod. DIN 931 Partially Threaded Hex Cap Screw still provides great convenience for technicians in actual operation.
