• Length is measured as overall total length; all adopt standard UNC coarse thread. Widely used for fixing gears, shafts, pulleys and small precision components
• Corrosion‑Resistant 304 Stainless Steel Construction:All Set screws are manufactured from solid 304 stainless steel. It provides superior anti‑oxidation and chemical corrosion resistance and may be mildly magnetic. Burr‑free uniform coarse threads support repeated assembly and disassembly, more durable than carbon steel fasteners
• Internal Hex Allen Socket Structure:Recessed internal hex drive fits standard allen wrenches perfectly without slipping during torque adjustment. No protruding external head, saves installation space and avoids surface scratch interference
• High‑Grip Sharp Cup Point Tip:The thin sharp edge on cup point tip digs into metal contact surfaces tightly after tightening, effectively preventing rotation and loosening caused by mechanical vibration, far better locking performance than flat point set screws
• Rotatable Round Compartment Storage Organizer:Comes with rotatable circular plastic drill storage case with independent divided slots. Rotate the tray to quickly switch between different screw sizes for instant identification. Compact lightweight rotary design saves space, easy to carry for maintenance workshops, laboratory assembly and home precision DIY projects
