Socket Head Cap Screws – High Torque Fastening for Precision Assemblies
Product Description
Socket Head Cap Screws (SHCS) are premium-grade fasteners engineered for high-strength, precision applications. Known for their cylindrical head and internal hex drive, they allow for maximum torque transmission in tight or recessed spaces. Manufactured as per DIN 912, ISO 4762, and ASTM A574 standards, these screws are ideal where strength, reliability, and clean aesthetics are crucial.
