Double end stud with nibs on flange

a) A step shoulder pin has a shoulder, or stepped section, where the diameter changes. This creates a larger diameter at one end of the pin, forming a "step." Unlike threaded pins, these pins do not have threads along their length. They are smooth and cylindrical.

b) Step shoulder pins are used in applications where precise alignment, and secure positioning are required.

a.) These type of screws are distinguished by the direction in which they tighten and loosen. Their main difference is their direction of rotation.

b.) Right-hand thread screw - Standard screws, tightened when turned clockwise and loosen when turned counterclockwise, used in most applications.

c.) Left-hand thread screw - Non-standard screws, tighten counterclockwise, primarily used in power or safety-related situations.

This stud pin is produced using open die forming and features a cylindrical knurled head and a specially designed pin shape.

Special design for an internal thread tube, mushroom head, partially knurled body

a.) A double-ended threaded rod is a type of fastener that features threading on both ends of the rod, with a section in the middle that may or may not be threaded.

b.) This design allows the rod to be used in applications where two components need to be joined, often with nuts or other fasteners securing the ends.

a.) 焊接螺栓是一種螺紋緊固件，當一旦與對手件鉚合後，即可提供耐用且可靠的固定。 通常這些螺栓在其頭部上方或下方會有不同形狀的“焊接點”，可因應不同產業需求自訂, 來滿足特定的要求。

b.) 此焊接螺栓具有 360° 的凸出焊接圈，其可提供全面密封，防止油、空氣或水洩漏； 春澤可提供各種螺紋外徑、材料、及尺寸的工業用焊接緊固件。
