Value Collection 41920 Button Socket Cap Screw M5x0.8

Product Description

The VALUE COLLECTION 41920 is a fully threaded button socket cap screw built to ISO 7380-1 standards. It features an M5x0.8 metric thread and a 30 mm length under the head, driven by a 3 mm hex socket. Manufactured from alloy steel at a material grade of 10.9 and finished with a black oxide coating, this fastener delivers high tensile strength with moderate corrosion resistance. It is intended for use by machinists, maintenance technicians, and mechanical assemblers who require a low-profile head profile with reliable clamping force in structural or mechanical assemblies.

This screw is suited for general industrial, mechanical, and equipment assembly applications where a flush or recessed head style is required. The button head profile distributes clamping load across a wider bearing surface than a standard cap screw, making it a practical choice for sheet metal assemblies, enclosures, jigs, and fixtures. Right-hand thread direction follows standard metric fastener convention. The black oxide finish reduces surface reflectivity and provides light rust inhibition in dry or lightly protected indoor environments.

Key Features

• M5x0.8 metric thread with right-hand direction and 4G/6G thread fit class
• 30 mm length under head for medium-depth fastening applications
• 3 mm hex socket drive for use with standard Allen keys or hex drivers
• Grade 10.9 alloy steel construction for high tensile strength
• Black oxide finish reduces reflectivity and provides light surface protection
• Fully threaded per ISO 7380-1 fastener standard

Compatibility

Designed as an ISO 7380-1 compliant metric button socket cap screw suitable for M5 threaded holes in industrial equipment, mechanical assemblies, and structural applications requiring a low-profile head.

Installation Notes

Installation should be performed by qualified machinists or mechanical technicians using a calibrated torque wrench and the correct 3 mm hex key or socket driver. Always verify thread fit and hole depth before installation to avoid cross-threading or bottoming out. Do not exceed the rated grade 10.9 proof load. Follow applicable machine design standards and equipment manufacturer guidelines for fastener torque requirements.
