Low-Profile Self-Locking Captive Screws DIN-Compliant Anti-Vibration Machine Fasteners In Stainless Steel, Titanium Custom Sizes

Low-Profile Self-Locking Screws (also known as Flush-Mount Captive Screws) are engineered for space-constrained applications, offering a shallow head height compared to standard Socket Cap Captive Screws. These anti-vibration machine screws integrate an unthreaded shank below the head, ensuring partial removal when paired with Threaded Captive Washers for secure, self-retaining assemblies.

Widely used in industrial machinery, military systems, and automotive captive screw solutions, these DIN standard self-locking screws meet stringent EU directives for safety-critical equipment. Their tamper-resistant security screw design prevents unauthorized disassembly, while precision self-locking fasteners guarantee alignment accuracy in high-stress environments.

Crafted from durable stainless steel low-head screws (A2/304 or A4/316 grades), we also offer specialized materials like Titanium and Aluminum for custom non-removable screws tailored to extreme conditions. Available in metric screws (M3–M20) with lengths up to 300mm, optional thread-locking patch screws enhance vibration resistance in dynamic applications.

Our fastener manufacturing expertise extends to bespoke solutions: non-standard sizes, finishes, and low-volume orders for precision self-locking fasteners are supported (minimum order quantities apply). Explore GuanBiao’s full range of ISO standard screws, including security-grade and high-tensile screws, designed for aerospace, electronics, and heavy machinery.
