Screw M8*55-Hexagon socket head screw

Screw M8*55-Hexagon socket head screw is a metric fastener designed for precise, reliable clamping in metal-to-metal assemblies. With an 8 mm diameter and a 55 mm length, this hex socket head cap screw is ideal for deeper mounting points where standard short screws won’t reach, delivering a clean, secure installation every time.

• Clear, space-saving drive — hex socket (Allen) drive provides a flush profile that sits neatly within frames, brackets, and machinery housings, reducing snag hazards in tight spaces.
• Standardized M8 thread — designed to pair with compatible M8 nuts and tapped holes, enabling straightforward integration into common mechanical builds, automation fixtures, and DIY projects.
• Long reach for sturdy assemblies — at 55 mm, this screw accommodates thicker components or multiple joined plates where a longer fastener is required to achieve solid, vibration-conscious clamping.
• Versatile use cases — popular in frame constructions, equipment mounting, robotics chassis, 3D printer frames, and other precision assemblies where a reliable, clean-fastener appearance matters.
• Practical installation tips — ensure the mating hole or nut is clean and properly aligned, engage threads gradually to avoid cross-threading, and consider a suitable thread locker if the application experiences significant vibration or dynamic loads.

This screw is ideal for engineers, technicians, and DIY enthusiasts who demand a dependable, metric fastener that combines a compact Allen-drive head with the reach needed for robust assemblies. When you need a precise, long M8 hex socket head screw that delivers consistent performance across frames, brackets, and housings, this M8×55 screw is a reliable choice that fits naturally into standard metalwork workflows.
