SS M5x50L Allen Head Screws (10pcs)
The SS M5 x 50mm Allen Head Screw is a heavy-duty fastener designed for structural applications requiring significant reach and superior load-bearing capacity. Forged from 100% Genuine 304 Stainless Steel (A2-70/A4-70), these screws are engineered to provide a high level of chemical and corrosion resistance, making them suitable for marine, industrial, and outdoor environments where standard steel would fail.
Key Features
These Socket Head Cap Screws feature precision-cut M5 metric threading and a specialized knurling on the head, which provides extra grip during manual handling or specialized socket applications. The deep internal hex drive is designed for a 4mm Allen key, allowing for high-torque tightening without the risk of stripping or deforming the head. With a 50mm shank length, these bolts are ideal for fastening thick components or creating secure through-bolt connections.
Versatile Applications
The M5 x 50mm sizing is a staple in mechanical engineering and robust DIY projects:
Machinery Assembly: Securing heavy motor mounts, industrial brackets, and structural frames.
Automotive & Marine: Ideal for engine bay components or deck hardware where saltwater exposure is a concern.
Construction: Perfect for assembling workbenches, heavy-duty shelving, and outdoor furniture like headboards or cabinets.
Robotics: Used in larger UAV frames or ground robot chassis to connect multi-layered structural plates.
