The M8 SEM Hex Tap Bolts Philips Head Machine Screw with Flat/Spring Washer is a high-quality stainless steel SEMS screw designed for durability, corrosion resistance, and ease of use. Manufactured from SS304 stainless steel, this screw ensures long-lasting performance in demanding applications, making it suitable for industrial, construction, automotive, machinery, and household projects.

SEMS screws (also called SEM screws) are machine screws with lock washers pre-assembled under the head, eliminating the need for separate washer installation. This design saves time, reduces assembly costs, and ensures the washer stays in place, preventing loss during maintenance or operation. The integrated flat and spring washer combination provides extra grip, vibration resistance, and secure fastening, extending product life and enhancing reliability.

These screws are widely used in electrical enclosures, electronic devices, metal assemblies, and machinery where vibration-proof fastening and consistent torque are required. The Philips head allows easy tightening with standard screwdrivers or power tools, while the hex tap design ensures a strong hold in pre-threaded or tapped holes.
