Hex bolts have hexagonal heads and machine threads for use with a nut or in a tapped hole. Also known as hex cap screws or machine bolts.
Fine-pitch hex head bolts are specified to meet the special requirements for coarse threading. The fine thread also has a pitch series. It is mainly used in hydraulic system metric fittings, mechanical transmission parts, thin-walled parts with insufficient strength, and space. Restricted internals and shafts with high self-locking requirements.
Fine pitch hex head bolt thread measuring method
1. Measuring the angle of the thread The angle of the thread is also called the angle of the tooth. The measurement of the angle of the thread can be achieved by measuring the side angle, which is the angle between the side of the thread and the vertical plane of the thread axis. The approximate contour of the thread is sampled in straight segments on both sides of the thread, and a linear least squares fit is applied to the sample points.
2. The measuring pitch of the pitch refers to the distance between a point on the thread and the corresponding point on the adjacent thread. The measurement must be parallel to the thread axis.
3. Measurement of the diameter of the thread The diameter of the thread is the distance between the medium diameter line and the axis, and the medium diameter line is an imaginary line.
