Product: TA2 internal hex (Allen) screw Material: TA2 commercially pure titanium Standard: Manufactured to GB70.1 Surface finish: None (bare titanium) Key benefits Corrosion resistance: TA2 pure titanium resists seawater, many chemicals and outdoor environments, reducing fastener failure and maintenance needs. Lightweight and strong: High strength-to-weight ratio lowers overall assembly weight while maintaining reliable clamping performance. Non-magnetic and electrically compatible: Suitable for applications sensitive to magnetism or where titanium’s electrical properties are required. Clean, long-lasting finish: Supplied without plating or coating, preserving the natural titanium surface and avoiding flaking or galvanic issues from dissimilar coatings. Standard compliance: Produced to GB70.1 to ensure consistent dimensions and fit with standard mating parts and tools. Function and compatibility Designed as an internal hex (Allen) screw: fastens assemblies using a matching hex key or driver bit sized per the GB70.1 specification. Compatible with standard threaded holes, nuts, and components specified to GB70.1 tolerances or equivalent metric standards. Available in the TA2 grade of pure titanium, preferred when corrosion resistance and low weight are priorities. Performance and handling notes No surface treatment: delivers native titanium performance and color; suitable where coatings are undesirable or when secondary surface finishing (anodizing, passivation) will be applied by the customer. Durable in corrosive and marine environments; performs well in humid, salt-laden, and chemically aggressive conditions. Non-magnetic property makes the screw suitable for sensitive instrumentation and electronic housings. Typical applications Marine and offshore hardware: fastenings on boats, deck fittings, and exposed assemblies where corrosion resistance and low weight extend service life. Lightweight structural assemblies: bicycles, UAVs, and transport components where reducing mass without sacrificing reliability is critical. Chemical processing, laboratories, and outdoor equipment: fixtures and enclosures exposed to corrosive media or frequent moisture. Sensitive equipment housings: electronic enclosures, sensors, and instruments that require non-magnetic fasteners. Ordering and selection tips Confirm the required thread size, length, and hex key size per GB70.1 when placing an order to ensure correct fit. If a coated or colored finish is required, specify post-treatment options separately; this product is supplied without surface treatment.
