Category: Metal Lathes Name: Left and Right Thread Double End Thread Rod Bar Headless Stud Bolts Material: 304 A2 Stainless Steel Standard: GB Thread Diameters: M4 (4mm), M5 (5mm), M6 (6mm), M8 (8mm), M10 (10mm), M12 (12mm), M16 (16mm) Key benefits Dual end threads with opposite directions enable fastening from both sides, simplifying assembly in tight spaces and reducing the need to flip components. Headless design provides unobtrusive mounting through plates or workpieces and allows flush installations where a protruding head would be problematic. Made from 304 A2 stainless steel, offering good corrosion resistance and durability for general structural and mechanical use. GB standard ensures compatibility with GB threaded components and fittings, helping ensure reliable mating with corresponding nuts and hardware. Available in a wide range of sizes (M4 to M16) to suit different applications and load requirements. Durable and dependable for equipment, fixtures, and assemblies where a stable, longlasting fastener is needed. Applications and use scenarios Machinery and equipment assembly: used to fasten components through a plate or body with nuts on both sides, leveraging the left and right thread configuration for secure clamping. Automotive and chassis mounting: suitable for mounting brackets or subsystems that require throughbolts with nuts on opposite sides for even load distribution. DIY and fabrication projects: ideal for building frames, jigs, or fixtures that pass a fastener through a panel and require tightening from both sides for alignment and stability.
