Questions about this product
- What makes these shoulder screws different from regular bolts?
- They have an unthreaded shoulder below the head that acts as a smooth bearing or pivot surface. That lets parts rotate around them, so they work as axles for rollers, pulleys, and levers. Regular bolts can't do this cleanly.
- What sizes and how many screws come in the pack?
- You get 10 pieces, with M3, M4, M5, and M6 thread sizes available in the kit. That range covers fine electronics up to heavier machinery. The shoulder diameter and length aren't listed, so check those against your design.
- Will these rust outdoors?
- They're 304 stainless steel, which resists oxidation and many chemicals well. That makes them suitable for damp and outdoor mechanical use. The hex socket cap head also lets you torque them tightly in confined spaces.
