Value Collection 427350MSC Flange Bolt M16 X 1.25 60mm

Product Description

The VALUE COLLECTION 427350MSC is a smooth flange bolt designed for metric fastening applications requiring a wide, integrated bearing surface. Manufactured from Grade 10.9 alloy steel with a phosphate and oil finish, this bolt delivers high tensile strength and corrosion resistance suitable for demanding industrial and mechanical assemblies. The smooth flange distributes clamping load over a larger area than a standard hex bolt, reducing surface damage and the need for a separate washer. The partially threaded shank provides a consistent grip length, making it appropriate for applications where shear loads and precise joint control matter.

This bolt is used in machinery, automotive, and general industrial assembly applications where metric DIN-standard fasteners are specified. The M16 x 1.25 fine thread pitch provides greater resistance to loosening under vibration compared to coarse-thread alternatives. With a 60 mm length under head and 30 mm of threaded engagement, it suits medium-depth through-bolt and tapped-hole installations. Mechanical and maintenance trades working on equipment that requires DIN 6921 compliant fasteners will find this bolt meets the dimensional and strength requirements of that standard.

Key Features

• Grade 10.9 alloy steel construction for high tensile and proof load ratings
• Phosphate and oil finish for moderate corrosion protection and consistent installation torque
• Smooth flange eliminates the need for a separate flat washer in many applications
• Fine thread pitch (M16 x 1.25) improves vibration resistance compared to coarse M16 thread
• Partially threaded shank maintains grip length accuracy for controlled joint clamping
• Conforms to DIN 6921 and DIN ISO 898-1 standards for dimensional and mechanical compliance

Compatibility

Designed as a DIN 6921 compliant smooth flange bolt for metric M16 x 1.25 fine-thread tapped holes and through-bolt assemblies in industrial machinery, automotive, and general mechanical applications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians familiar with metric fastener torque specifications for Grade 10.9 hardware. De-energize and lock out all equipment before fastener service. Use a 12.73 to 13.00 mm hex drive for proper fit. Do not use impact tools at full power without a controlled torque finishing pass, as Grade 10.9 fasteners have specific proof load limits that must not be exceeded.
