We are engaged in offering MS Hex Head Self Drilling Screw  product to our clients. Our range of this products is widely appreciated by our clients.

A truss head drilling screw is a fast, efficient fastener with a wide, low-profile domed head and a drill-point tip, eliminating pilot holes by drilling its own path through thin metal or other materials for secure, load-distributing fastening in HVAC, roofing, and construction. Its large head creates a bigger bearing surface for better grip, preventing pull-through on soft or thin surfaces

A Truss Head self-tapping screw (also Type BT or Type 25) is a specialized thread-cutting fastener, featuring spaced, blunt-pointed threads with cutting edges, designed to form its own mating threads in softer materials like plastics, wood, and composites, eliminating the need for pre-drilling and providing strong holding power

A cheese head screw is a precision fastener with a distinctive cylindrical, flat-topped head, about half its diameter in height, resembling a small wheel of cheese, often using a simple slot drive (DIN 84) for a flush finish, offering high torque and used in machinery, electronics, and appliances for durability and neat appearance, commonly in stainless steel or alloy steel

A B Type Thread Screw is a versatile fastener for joining sheet metal (0.050"-0.200" thick), plastics, or plywood, featuring a larger root diameter and finer thread pitch for a strong grip, often needing a pilot hole and available in various heads (pan, hex) and drives (Phillips, slotted) for secure thread-forming in softer materials

A Button Head Cap Screw (or socket button head cap screw) features a low, smooth, rounded head with a hexagonal (Allen) drive, offering a sleek, streamlined look with minimal protrusion, ideal for aesthetics and limited space in machinery, electronics, and furniture, providing good load distribution and resistance to loosening due to its wide bearing surface, though usually for moderate torque applications. 

A pan head self-tapping screw is a versatile fastener with a rounded, low-profile head (providing a wide bearing surface for secure clamping) and sharp threads that create their own mating hole in materials like wood, plastic, or thin metal, eliminating the need for pre-tapping, often featuring a Phillips drive for easy driving, offering a clean, flush finish in assemblies. 

A Hex Head Lag Bolt Screw, or lag screw, is a heavy-duty fastener, essentially a large wood screw with a hexagonal or square head, thick coarse threads, and a pointed tip, designed for high-strength connections in wood, timber, or wood-to-metal applications, requiring a pilot hole for installation and providing superior holding power for heavy loads
