Set Screws (Current Product) | Sewing machines, machinery parts | Material: Stainless Steel (AISI 304) ▲ Corrosion Resistance: Passes ASTM B117 (1000 hours) ▲ Torque Capacity: 12 Nm (ISO 6789) | High durability, corrosion-resistant, precision fit for delicate machinery | Higher cost, application-specific design, requires exact threading alignment |
Hex Cap Screws | Heavy machinery, construction | Tensile Strength: Grade 8 (150 ksi) ▲ Thread: UTS #8-32 (ANSI B1.1) Head Design: Hexagonal (ASTM F488) | Exceptional load-bearing capacity, durable for heavy-duty use | Requires wrench for installation, bulkier profile limits space-constrained use |
Socket Head Screws | Aerospace, electronics | Metric Thread: M6x12 (ISO 261) Tensile Strength: 1200 MPa (EN 10204) Socket Head: ISO 14579 | Compact profile, high strength for tight spaces, precision engineering | Requires hex key, costly, brittle under extreme torque |
Machine Screws | General assembly, DIY projects | Thread: #6-32 (ANSI B1.1) Material: Carbon Steel (ASTM A307) Length: 1" (ISO 2768) | Affordable, versatile for basic applications, easy to source | Lower corrosion resistance, weaker than specialized screws, prone to stripping |
Self-Tapping Screws | Wood, plastic, soft metals | Self-Tapping: ASME B18.16.1 Tensile Strength: 550 MPa (ISO 898-1) Thread Pitch: 1.5 mm | No pre-drilling needed, quick installation in soft materials | Not suitable for hard surfaces, may strip threads in repeated use |
Locking Screws | Vibrating machinery, automotive | Threaded Locking: DIN 912 Corrosion Resistance: ASTM F1940 ▲ Torque Retention: 95% (ISO 16047) | Prevents loosening in dynamic environments, durable locking mechanism | Limited thread engagement, harder to remove after installation |
