Value Collection 42213 M20 X 2.50 X 90 Mm Hex Cap Screw

Product Description

The VALUE COLLECTION 42213 is a partially threaded hex head cap screw built to DIN 931 specifications. It features an M20 x 2.50 metric thread with a 90 mm length under the head and a 30 mm hex drive size. Manufactured from Grade 8 steel with a zinc-plated finish, this fastener delivers high tensile strength with basic corrosion resistance. It is a standard metric fastener suited for heavy mechanical assemblies, structural connections, and equipment fabrication where a partially threaded shank is required for precise clamping and bearing-load applications.

This cap screw is used in commercial and industrial settings where metric fasteners are specified. Typical applications include machinery assembly, steel fabrication, HVAC equipment mounting, and general structural bolting. The partial thread design allows the unthreaded shank to bear shear loads, making it appropriate for bolted joints where lateral force resistance is a design requirement. Installers working on metric-spec equipment in any trade will find this a direct-fit fastener for standard M20 x 2.50 threaded holes.

Key Features

• M20 x 2.50 metric thread — compatible with standard DIN 931 tolerances
• 90 mm length under head for use in deep-reach or thick-material applications
• Grade 8 steel construction provides high tensile and yield strength
• Zinc-plated finish offers basic corrosion protection in dry to mildly humid environments
• Partially threaded shank supports shear load bearing in structural bolted joints
• 30 mm hex drive size — compatible with standard hex wrenches and impact sockets

Compatibility

Designed for use in standard M20 x 2.50 metric threaded applications conforming to DIN 931. Suitable for use with M20 hex nuts and washers in any metric-threaded assembly.

Installation Notes

Installation is performed with a 30 mm hex wrench or impact socket. Always verify thread engagement depth and mating thread condition before driving the fastener. Follow applicable torque specifications for Grade 8 metric fasteners as referenced in the relevant equipment service manual or structural design standard. Do not mix metric and imperial fastener hardware in the same bolted joint.
