Specifications of the Product

• 90 sets of 6 sizes: The Chicago rivet stud set includes 15 sets of each size (M5*4mm, M5*5mm, M5*6mm, M5*8mm, M5*10mm, M5*12mm). And with three different screw lengths (M4*3mm, M4*4mm, and M4*5mm), you can freely combine them. It is recommended that M5*10 and M5*12 column sizes be matched with M4*5 screws to be more secure. Various lengths are available to meet your different needs.
• Leather rivets are in high demand because they are strong and durable, easy to bind, have an excellent finish, good screw head chamfering, a low profile slot, a professional appearance, and are simple to disassemble and install.
• High-quality material: These Chicago screws are made of high-quality carbon steel, advanced nickel plating, and a stable and dense oxide film on the surface, which prevents them from coming loose.
