Socket Screws
Our metric and inch-sized socket screws meet international standards including ASME, ISO, and ASTM specifications. Available in grades up to 12.9 tensile strength, these fasteners feature precision-engineered head designs for optimal torque transmission. We manufacture various types including cap screws, shoulder screws, and countersunk variants to suit aerospace, automotive, and industrial applications.
Durlok Fasteners
Proprietary self-locking fasteners designed to maintain secure connections under extreme vibration conditions. Available in bolt, nut, and washer configurations with hardness ratings between HRC 28-36. These components provide reliable performance in heavy machinery, transportation systems, and industrial equipment requiring enhanced joint integrity.
Structural Assemblies
High-strength structural fastening systems compliant with BS EN 14399 and ASTM standards. Our range includes pre-load bolts, tension control assemblies, and heavy hex components in grades up to 10.9. These solutions meet critical requirements for bridge construction, steel frameworks, and industrial infrastructure projects requiring guaranteed load-bearing performance.
Stainless Steel Components
Austenitic stainless steel fasteners in A2 and A4 grades (304/316 equivalent) manufactured to DIN, ISO, and ASME specifications. Available in socket head, hex bolt, and threaded rod configurations with tensile strengths up to 800MPa. These components provide excellent corrosion resistance for marine, chemical processing, and food industry applications.
Petrochemical Studbolts
Specialised stud bolts and companion nuts designed for high-pressure, high-temperature environments in refineries and petrochemical plants. Manufactured to ASTM A193/A194 standards in materials including B7, B8, and L7 alloys. These components ensure reliable performance in flanged joint assemblies operating under extreme service conditions.
