Value Collection 643439PR Hex Head Cap Screw M14 X 2.00 Grade 8.8

Product Description

The VALUE COLLECTION 643439PR is a metric hex head cap screw designed for general mechanical fastening in industrial, commercial, and maintenance applications. Manufactured from Grade 8.8 steel with a bright uncoated finish, this fully threaded fastener measures M14 x 2.00 thread size with an 80 mm length under head. The 22 mm hex drive size accommodates standard open-end, box-end, and socket wrenches. Grade 8.8 steel provides a balance of tensile strength and ductility suited to bolted joint assemblies where controlled clamping force is required. It is installed by millwrights, maintenance technicians, machine builders, and general contractors working with metric-dimensioned equipment and structures.

This screw is used wherever a metric fully threaded hex head fastener is required, including machinery frames, equipment mounting, structural steel assemblies, and fabrication work. The fully threaded shank allows engagement along the entire bolt length, making it well suited for thinner material stacks or applications where the threaded portion must extend to the bearing surface. Conformance to DIN 933 and ISO 4017 standards ensures dimensional consistency with metric hardware sourced from multiple suppliers.

Key Features

• Fully threaded shank for maximum thread engagement across the full 80 mm length under head
• Grade 8.8 steel construction provides a minimum tensile strength of 800 MPa per DIN and ISO material classification
• M14 x 2.00 metric thread pitch conforms to standard metric coarse thread series
• 22 mm hex drive accepts common metric wrenches and impact sockets
• Bright uncoated finish suitable for indoor use or subsequent coating by the installer
• Manufactured to DIN 933 and ISO 4017 dimensional standards for interchangeability

Compatibility

Designed as a standard metric replacement or new-installation fastener conforming to DIN 933 and ISO 4017 specifications, compatible with any M14 x 2.00 metric coarse threaded nut or tapped hole meeting the same standards.

Installation Notes

Installation is performed by hand-threading the fastener into a clean, properly tapped M14 x 2.00 hole before final torque is applied with a calibrated torque wrench or impact driver set to the appropriate specification for the application and joint design. Inspect mating threads for damage or contamination before assembly. Do not use an impact tool without confirming thread engagement to avoid cross-threading. For structural or safety-critical joints, consult applicable engineering standards for torque values and joint preload requirements.
