Value Collection 815228PS M20 Hex Cap Screw Grade 8.8 Zinc

Product Description

The VALUE COLLECTION 815228PS is a metric hex head cap screw designed for general industrial and mechanical fastening applications. This partially threaded fastener is manufactured from Grade 8.8 steel with a zinc-plated finish, providing a balance of tensile strength and corrosion resistance. It measures M20 x 2.50 mm in thread size with a 60 mm length under head and a 30 mm hex drive. Grade 8.8 steel indicates a minimum tensile strength of 800 MPa, making it suitable for medium-to-high load structural and equipment assemblies. Manufactured to DIN 931 and ISO 4014 standards, this screw offers consistent dimensional tolerances expected in metric fastener applications.

This fastener is used across a wide range of industrial, mechanical, and construction applications where a reliable metric hex head cap screw is required. The partial thread shank is appropriate for through-bolt assemblies and applications requiring shank bearing against clamped surfaces. Typical use cases include equipment frames, machinery bases, structural steel connections, and general fabrication work. It is commonly installed by millwrights, pipefitters, ironworkers, and maintenance technicians working in both light and heavy industrial environments.

Key Features

• M20 x 2.50 mm thread size with 60 mm length under head for deep-clearance fastening applications
• Grade 8.8 steel construction provides high tensile strength for demanding mechanical assemblies
• Zinc-plated finish offers moderate corrosion resistance in standard indoor and light outdoor environments
• Partially threaded shank per DIN 931 and ISO 4014 standards ensures consistent dimensional compliance
• 30 mm hex drive size is compatible with standard metric wrenches and sockets
• Metric thread standard ensures interchangeability with other ISO-compliant hardware

Compatibility

Designed as a DIN 931 and ISO 4014 compliant metric hex head cap screw, suitable for use in any application requiring an M20 x 2.50 mm partially threaded fastener in Grade 8.8 steel.

Installation Notes

Installation should be performed by qualified mechanical, maintenance, or construction personnel using appropriately rated metric hand tools or power tools. Always verify that mating threads and tapped holes conform to the M20 x 2.50 mm metric standard before installation. Avoid overtightening, which can exceed the proof load of the fastener or damage mating materials. Follow applicable industry standards and engineering specifications for fastener torque values based on joint design and application requirements.
