Special hex socket flange head screws with cutting thread

This multi-tooth bolt features a drive head with 12 contact points, enhancing torque transmission and reducing the risk of tool slippage.

These hex head screws with two sides cutting are designed to simplify installation in various materials.

A special double threaded screw with shoulder is a fastener designed with two distinct threaded sections and an integrated shoulder for precise positioning and alignment.

a.) These screws combine the attributes of a flange-headed bolt with a triangular head. This unique design requires a matching triangular driver for installation or removal.

b.) These bolts are excellent at providing minimal tamper resistance and security. While these bolts provide some level of security, they are not as secure as other security screws. Therefore, caution should be exercised when using them in applications where security is paramount.

a) Clinch studs, also known as self-clinching studs, are fasteners used in sheet metal fabrication and other applications where strong, permanent fastening is required. They typically consist of a threaded stud with a knurled or serrated shank and a flat or flanged head.

b) The installation process involves inserting the clinch stud into a pre-punched or drilled hole in the metal sheet. Then, using a press or similar tool, the knurled portion of the stud is compressed into the surrounding metal, creating a secure and permanent attachment without the need for welding or additional hardware. They offer advantages such as high strength, resistance to vibration, and a low-profile installation.

a) External hexalobular socket (6 lobe) / metric thread / tapping thread for both ends. 

b) A double-end stud with collar is a type of fastener that features threaded ends on both sides and a non-threaded central collar or flange. Thread types of both sides can be customized according to customer's request, differen surface treatment is available upon request.
