Set Screw Product Describsion

Set screws are Boltead’s main product. We are a manufacturer of set screws and also a supplier of set screws. While producing and supplying set screws, we also produce nuts, washers and other fastener products used in conjunction with them.

The set screws we produce are generally classified according to whether the material is carbon steel, stainless steel or brass. More specific classifications are as follows:

Carbon steel set screws are generally classified according to strength levels. The more common strength levels are: 4.8, 8.8, 10.9, and 12.9. Among them, bolts with grade 8.8 or above are generally called high-strength bolts （high tensile bolts）.Stainless steel set screws are generally classified according to different materials. The more common stainless steel materials are SUS201 SUS304 SUS316

In addition to different materials and strengths, the biggest impact on set screws is surface treatment. The following are the more common surface treatments for set screws: black oxide, black zinc, zinc plated (ZP), color zinc plating (CZP /YZP), hot dip galvanized (HDG), dacromet coating, etc.

Set Screw Production Process

Set screws are sent from the raw material line to the final product. They generally go through the following process:
Annealing of raw materials – pickling – drawing – forming – grinding – heat treatment – surface treatment – classification – packaging – shipping

The rough schematic diagram is as follows:

Set Screw Application fields

• Set screws are commonly used to secure an object within or against another object, making them suitable for applications where a non-permanent, adjustable fastening is needed.
• They are frequently employed in machinery and mechanical systems to fix components such as gears, pulleys, or shafts onto a rotating or stationary part.
• Set screws are often utilized in manufacturing and assembly processes to hold parts in place, provide alignment, or prevent movement of components.
• They are also used in woodworking and carpentry to secure handles, knobs, or other fittings onto shafts or axles.
• Set screws find application in various industries such as automotive, aerospace, construction, and consumer goods manufacturing, due to their versatility and ability to provide a strong, reliable connection.
