Value Collection 815227PS Hex Head Cap Screw M20x2.5

Product Description

The VALUE COLLECTION 815227PS is a metric hex head cap screw built to DIN 933 and ISO 4017 standards. Made from grade 8.8 steel with a zinc finish, this fully threaded fastener is designed for structural and mechanical applications where reliable clamping strength is required. The M20x2.5 thread and 45mm length under head make it a commonly specified size in heavy equipment assembly, structural steel connections, and industrial maintenance. Installation requires a 30mm hex key or wrench. This screw is sold individually with a minimum order quantity of 10 units.

This fastener is appropriate for metric-specified applications across manufacturing, fabrication, construction, and general mechanical assembly. The grade 8.8 rating indicates medium-high tensile strength, suitable for joints that require consistent preload without the brittleness of higher-grade fasteners. Fully threaded along the shank, it provides thread engagement across the entire length under head, which is preferred in through-bolt configurations and applications where the full thread depth is needed for secure nut engagement.

Key Features

• Grade 8.8 steel construction for reliable tensile and yield strength in structural applications
• Fully threaded shank per DIN 933 and ISO 4017 standards
• M20x2.5 metric thread size with 45mm length under head
• Zinc finish provides basic corrosion resistance for indoor and light-duty outdoor use
• 30mm hex drive size compatible with standard metric wrenches and sockets
• Metric thread standard for use with ISO-spec nuts and hardware

Compatibility

Designed for use with M20x2.5 metric hex nuts and ISO-standard threaded inserts in applications conforming to DIN 933 or ISO 4017 fastener specifications.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or structural assemblers using a 30mm combination wrench or socket. Always confirm thread engagement and joint material compatibility before installation. Follow applicable engineering or structural specifications for preload and torque requirements specific to your application. Do not install in corrosive or high-moisture environments without verifying that a zinc finish provides sufficient protection for the service conditions.
