Value Collection HC3X18030-010BX M18 Hex Cap Screw

Product Description

The VALUE COLLECTION HC3X18030-010BX is a fully threaded hex head cap screw manufactured to metric standards for use in mechanical assembly, structural fastening, and industrial maintenance applications. It is sized M18 x 2.50 with a 30 mm length under the head and features a 27 mm hex drive. Constructed from 18-8 austenitic Grade A2 stainless steel, it offers solid corrosion resistance without any additional coating. This fastener conforms to DIN 933, EN 24017, and ISO 4017 standards, making it suitable for applications where dimensional and material traceability is required. Installers working in corrosive or washdown environments commonly specify Grade A2 stainless for this reason.

This cap screw is used across a broad range of trade and industrial settings including HVAC equipment mounting, plumbing system assemblies, electrical enclosure fabrication, and pool or water treatment equipment where moisture exposure is a factor. Its fully threaded shank makes it well suited for through-bolting and applications requiring engagement along the full length of the fastener. The metric M18 x 2.50 thread pitch is standard in European and globally specified equipment.

Key Features

• M18 x 2.50 thread size with 30 mm length under head for precise metric fitment
• Fully threaded shank provides maximum thread engagement throughout the fastener length
• 18-8 austenitic Grade A2 stainless steel construction for corrosion resistance in wet or outdoor environments
• Bright uncoated finish maintains dimensional accuracy without coating buildup on threads
• Conforms to DIN 933, EN 24017, and ISO 4017 standards for dimensional compliance
• 27 mm hex drive accommodates standard metric wrenches and sockets

Compatibility

Designed as a standard metric hex head cap screw conforming to DIN 933, EN 24017, and ISO 4017, suitable for any application specifying an M18 x 2.50 fully threaded fastener in 18-8 stainless steel.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with metric fastener specifications. Verify thread engagement and mating material compatibility before installation, particularly when fastening into aluminum or softer alloys. Use a calibrated torque wrench sized for a 27 mm hex drive and follow the torque specifications provided by the equipment or assembly manufacturer. Avoid mixing stainless fasteners with carbon steel hardware in the same assembly to prevent galvanic corrosion.
