Socket head screw plugs provide reliable sealing for hydraulic, automotive and machinery systems — withstanding high pressure while allowing easy access for maintenance and fluid changes.
The alloy trumpet-head self-tapping nut cuts its own thread in wood, plastic and soft alloys, with a flared head that spreads load. A smart fastening solution for machinery, electronics and furniture.
Nickel plating upgrades socket head (pan head) screws with superior corrosion resistance, wear resistance and a clean appearance — ideal for electronics, precision instruments and outdoor equipment.
The six-claw grounding washer (grounding disc-spring lock washer) delivers reliable electrical grounding and anti-loosening in rail, electrical, elevator and machinery applications.
Since the screw was invented in 1550, preventing loosening has been a constant challenge. Learn the three mature anti-loosening methods: friction, mechanical and permanent locking.
Resin screws are made to JIS and ISO standards but differ from metal screws in production. Learn material selection (RENY, PPS, PEEK, VESPEL), torque handling and chemical-resistance notes.
Miniature screws for toys, models and earphones require high strength, small size, eco-friendly plating and easy installation. Jiali supplies custom miniature screw solutions with samples in stock.
Nylon (plastic) nuts provide excellent insulation, non-magnetism, heat resistance, light weight and corrosion resistance. Available in PA66, PC, PVDF and PP, in multiple shapes and thread standards (metric, UNC, BSW).
Why choose copper nuts? Excellent rust resistance, corrosion protection and thermal/electrical conductivity. Learn how copper nuts are used in faucets, valves, electrical switches and plastic injection molding.
