Combi Hex Bolt – Stainless Steel

Combination hex bolts feature an integrated assembly of a spring washer and flat washer permanently captured beneath the hexagonal head, all manufactured in stainless steel. The spring washer provides anti-loosening action under vibration and thermal cycling, while the flat washer distributes the bearing load and protects the mating surface. Being fully stainless steel, this combination is ideal for panel fascia, electrical enclosures, control cabinets, and outdoor installations where both corrosion resistance and vibration resistance are required. The pre-assembled unit eliminates loose components, reduces assembly errors, and ensures consistent torque during high-volume production. Available in SS 304 for general use and SS 316 for marine or harsh chemical environments.
