Value Collection 42199 Hex Head Cap Screw M18 X 2.50

Product Description

The VALUE COLLECTION 42199 is a metric hex head cap screw designed for industrial and mechanical assembly applications requiring a strong, corrosion-resistant fastener. It features an M18 x 2.50 mm thread size with a 130 mm length under the head and is manufactured from Grade 8.8 steel — a medium-high-strength carbon steel grade suited to structural and machine assembly work. The zinc-plated finish provides a base level of corrosion protection. The screw is partially threaded and conforms to DIN 933 and ISO 4017 standards, making it a recognized metric fastener for specification-driven applications. This package contains 3 screws.

This fastener is used across a broad range of industrial, mechanical, and structural applications where metric hardware is specified. It is appropriate for equipment assembly, machinery maintenance, and general fabrication work. The Grade 8.8 rating makes it suitable for moderate-load structural connections. It is compatible with standard metric M18 hex nuts and washers. Machinists, millwrights, maintenance technicians, and general contractors commonly use this screw size in production and field settings where DIN or ISO metric standards are called out.

Key Features

• M18 x 2.50 mm metric thread with 130 mm length under head
• Grade 8.8 steel construction for medium-high tensile strength
• Zinc-plated finish for basic corrosion resistance
• Partially threaded shank per DIN 933 and ISO 4017 standards
• 27 mm hex drive size for standard metric wrenches and sockets
• Package quantity of 3 screws per order unit

Compatibility

Designed as a standard metric replacement or specification fastener for any application calling out an M18 x 2.50 x 130 mm partially threaded hex head cap screw per DIN 933 or ISO 4017.

Installation Notes

Installation is performed with a 27 mm metric wrench or socket. Always ensure mating threads are clean and free of debris before driving the fastener. Follow applicable mechanical or structural specifications for proper clamping load — do not substitute Grade 8.8 hardware in applications that specify a higher or lower strength grade without engineering review. Power down or de-energize any equipment before performing fastener maintenance on live assemblies.
