Value Collection 815229PS Hex Cap Screw M20x2.5 50mm Grade 8.8

Product Description

The VALUE COLLECTION 815229PS is a metric hex head cap screw designed for general-purpose bolted assemblies requiring a strong, corrosion-resistant fastener. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw offers a good balance of tensile strength and surface protection suitable for a wide range of structural and mechanical connections. The M20 x 2.50 thread size with a 50 mm length under head and full threading along the shank makes it well suited for through-bolt applications and flange connections. Machinists, millwrights, maintenance technicians, and field mechanics routinely specify this fastener for equipment assembly and structural fabrication work.

This fastener is used in metric-standard assemblies across industrial, commercial, and heavy equipment applications. The fully threaded shank allows maximum thread engagement in thinner materials or when used with a nut and washer configuration. It conforms to DIN 933 and ISO 4017 standards, making it interchangeable with other metric fasteners built to those specifications. Typical installations include machine frames, structural steel connections, conveyor systems, and general MRO repair work where a high-strength metric bolt is required.

Key Features

• Grade 8.8 steel construction provides high tensile and yield strength for demanding bolted joints
• Zinc-plated finish delivers baseline corrosion resistance for indoor and light outdoor environments
• Fully threaded shank for maximum thread engagement across the full 50 mm length under head
• M20 x 2.50 thread profile conforms to metric standard pitch specifications
• 30 mm hex drive size accommodates standard metric wrenches and impact sockets
• Meets DIN 933 and ISO 4017 standards for dimensional and mechanical consistency

Compatibility

Designed as an OEM-style metric fastener for any application requiring a DIN 933 or ISO 4017 compliant M20 x 2.50 hex head cap screw in Grade 8.8 steel.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a metric wrench or socket sized for the 30 mm hex. Always ensure mating threads are clean and free of debris before installation. Follow applicable torque specifications from the equipment manufacturer or relevant structural standards for Grade 8.8 M20 fasteners. De-energize and lock out equipment before servicing any bolted assembly.
