Value Collection HC3XX18080 M18 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION HC3XX18080 is a metric hex head cap screw sized M18 x 2.50 with an 80 mm length under head. It is manufactured from Grade 316 Austenitic Grade A4 stainless steel and left uncoated with a bright finish. The fully threaded shank engages the entire usable length, making it well suited for through-bolting and applications where maximum thread engagement is required. This fastener meets DIN 933, EN 24017, and ISO 4017 standards. Machinists, millwrights, marine fabricators, and industrial maintenance technicians typically install this type of hardware in corrosion-exposed environments where standard carbon steel fasteners would be inadequate.

Grade 316 stainless steel provides superior resistance to chlorides and salt environments compared to Grade 304, making this screw appropriate for marine, coastal, chemical processing, and food-service installations. The M18 x 2.50 thread pitch and 27 mm hex drive are compatible with standard metric tooling. It is sold individually and is suited for both light fabrication and heavy structural fastening tasks where metric hardware is specified.

Key Features

• M18 x 2.50 metric thread with 80 mm length under head for deep engagement
• Fully threaded shank maximizes usable thread length
• Grade 316 Austenitic Grade A4 stainless steel for enhanced corrosion resistance
• Bright uncoated finish — no coating thickness to account for in tolerance-critical fits
• 27 mm hex drive accepts standard metric wrenches and sockets
• Meets DIN 933, EN 24017, and ISO 4017 standards

Compatibility

Designed for use in applications requiring ISO 4017, DIN 933, or EN 24017 compliant metric fasteners with an M18 x 2.50 thread specification.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or structural fabricators using a standard 27 mm metric wrench or socket. Always ensure mating threads are clean and free of debris before installation. When fastening into dissimilar metals in wet environments, consider appropriate isolation techniques to prevent galvanic corrosion. Apply thread lubricant or anti-seize compound as dictated by the application engineering specification.
