Value Collection 644027PS M6 Hex Cap Screw Grade 8.8 Steel

Product Description

The VALUE COLLECTION 644027PS is a metric hex head cap screw designed for bolted assemblies requiring precise thread engagement and reliable clamping force. It features an M6 x 1.00 thread form with a 55 mm length under the head and is partially threaded per DIN 931 and ISO 4014 standards. The fastener is manufactured from Grade 8.8 steel, indicating a medium-high strength carbon steel construction suitable for structural and mechanical applications. The bright, uncoated finish means no additional corrosion treatment is applied, making it appropriate for indoor or controlled-environment installations. A licensed mechanic, millwright, or maintenance technician installs this screw using a 10 mm hex key or appropriate hex socket drive.

This cap screw is used in metric bolted joint applications across general manufacturing, equipment assembly, machinery maintenance, and structural fabrication. Partial threading per DIN 931 and ISO 4014 makes it well suited for through-bolt configurations where the unthreaded shank provides a bearing surface or alignment function. It is appropriate for use in both light-industrial and heavy-equipment maintenance settings where metric fasteners and Grade 8.8 mechanical properties are specified by design or engineering standards.

Key Features

• M6 x 1.00 metric thread form, 55 mm length under head
• Grade 8.8 steel construction for medium-high tensile strength
• Partially threaded shank per DIN 931 and ISO 4014 standards
• 10 mm hex drive size compatible with standard metric hex sockets and wrenches
• Bright uncoated finish, no additional plating or coating applied

Compatibility

Designed as a standard metric replacement or maintenance fastener for bolted assemblies specifying an M6 x 1.00 partially threaded hex head cap screw to DIN 931 or ISO 4014.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician familiar with metric fastener standards. Verify mating thread condition and class before installation, and ensure the receiving hole depth and thread engagement meet the requirements of the assembly specification. Do not exceed the torque limits specified in the applicable engineering or equipment documentation for Grade 8.8 M6 fasteners. Use of thread-locking compound, washers, or other hardware should follow the original equipment or structural design requirements.
