Value Collection 42198 Hex Head Cap Screw M18 X 2.50

Product Description

The VALUE COLLECTION 42198 is a partially threaded hex head cap screw engineered to metric specifications for use in structural, mechanical, and industrial fastening applications. This screw is manufactured from Grade 8.8 steel with a zinc-plated finish, offering a reliable combination of tensile strength and corrosion resistance. The M18 x 2.50 thread profile runs 120 mm under the head, and the 27 mm hex drive accepts a standard metric wrench or socket. Machinists, millwrights, maintenance technicians, and equipment assemblers commonly install this fastener wherever a medium-to-high-strength metric bolt is required.

This hex head cap screw suits general industrial assembly, equipment mounting, and structural connections that call for a metric M18 thread. Its partial threading allows it to serve as a shoulder-style fastener in applications where an unthreaded shank is needed between the bearing surface and the nut. It meets DIN 933 and ISO 4017 standards, making it appropriate for use in projects that require documented fastener compliance. Three screws are included per package.

Key Features

• M18 x 2.50 metric thread with 120 mm length under head
• Grade 8.8 steel construction for medium-to-high tensile strength
• Zinc-plated finish provides basic corrosion resistance
• Partially threaded shank for applications requiring an unthreaded grip zone
• 27 mm hex head fits standard metric wrenches and sockets
• Meets DIN 933 and ISO 4017 fastener standards

Compatibility

Designed as a metric-standard replacement or service fastener for equipment, structures, and assemblies requiring an M18 x 2.50 partially threaded hex head cap screw conforming to DIN 933 and ISO 4017.

Installation Notes

Installation is typically performed by millwrights, maintenance mechanics, or equipment technicians using a metric wrench or socket sized to the 27 mm hex head. Always de-energize or lock out the equipment being serviced before fastener replacement. Apply thread engagement and clamping load appropriate to Grade 8.8 specifications per the applicable engineering standard or equipment service documentation. Do not mix metric and unified thread components in the same assembly.
