M5 x 0.8 Round Coupling Nuts — 12 pieces, 304 Stainless Steel Key benefits - Join or extend threaded connections quickly and reliably: connect two M5 threaded rods or lengthen M5 screws and bolts without welding or custom machining. - Durable, corrosion-resistant construction: made from 304 stainless steel for long service life indoors or outdoors; resists rust and corrosion in humid or exposed environments. - Precise, secure fastening: internal precision M5 x 0.8 thread provides high holding strength and reliable alignment for mechanical and structural applications. - Convenient pack size: 12 identical round coupling nuts for small projects, repairs, spares, or production use. Specifications - Thread size: M5 x 0.8 mm (internal) - Outer diameter: 8 mm - Height (length): 20 mm - Material: 304 stainless steel - Quantity: 12 x round coupling nuts Features and performance - Internal thread with round-bar design for a compact, low-profile coupling. - Machined/precision thread for consistent engagement and reduced play. - 304 stainless steel offers good mechanical strength and excellent corrosion resistance, suitable for repeated assembly/disassembly. - Designed specifically for fastening applications where two external M5 threads must be joined or where bolt/screw thread length must be extended. Compatibility and fit - Compatible with M5 threaded rods, M5 bolts and M5 screws (pitch 0.8 mm). Confirm that mating parts use standard M5 x 0.8 threads before installation. - Outer diameter 8 mm and height 20 mm — check clearance in housings, channels, or through-holes to ensure a proper fit. Typical use scenarios 1) Extending threaded rods: join two M5 threaded rods to create a longer rod for curtain rails, shelving supports, or suspension hardware. 2) Repair and retrofit: replace a damaged or corroded nut or extend a bolt when the original fastener is too short for a repair on furniture, fixtures, or machinery. 3) Mechanical assembly and prototyping: quickly join components or adjust assembly length in small machines, hobby projects, and prototype rigs where modular adjustments are needed. Important note - Verify thread size (M5 x 0.8) and the required length/clearance for your application before purchase to ensure compatibility.
