Glossary

A chamfer is a transitional edge between two surfaces, typically created by cutting or grinding the corner at an angle, most commonly 45 degrees. Chamfers are used to remove sharp edges, improve aesthetics, facilitate assembly, and reduce stress concentrations. For fasteners, chamfers are often applied to the ends of bolts or screws to help guide the part into a hole or make it easier to start threading a nut onto the fastener.

The angle at which the edge or corner of a part is cut or ground to create a beveled surface, commonly set at 45 degrees but varying based on design needs. In fasteners, this angle helps facilitate easier installation by providing a smooth lead-in edge.

A secondary machining service that modifies fasteners by cutting them to a specific length, forming threads by either cutting (removing material) or rolling (pressing threads into shape), and adding a chamfer, which is an angled edge at the start of the fastener’s threaded section. This service customizes fasteners to meet precise application requirements.
