Value Collection 643252PS Hex Head Cap Screw M12x1.25x30mm

Product Description

The VALUE COLLECTION 643252PS is a metric hex head cap screw designed for bolted assemblies requiring close-tolerance fastening. Manufactured from Grade 8.8 steel with a bright uncoated finish, this screw delivers reliable tensile strength suited to mechanical and structural applications across a range of industries. The M12 x 1.25 fine-pitch thread provides greater thread engagement per turn compared to standard coarse pitch, making it appropriate where vibration resistance or precise clamping load is important. At 30 mm under the head and fully threaded along its shank, it is installed by licensed mechanics, millwrights, and maintenance technicians using a 19 mm hex wrench or socket.

This fastener is used in metric-dimensioned equipment including industrial machinery, automotive assemblies, heavy equipment, and structural fabrication where fine-pitch M12 fasteners are specified. It conforms to DIN 961 and ISO 8676 standards, making it a direct fit wherever those dimensional standards are called out on engineering drawings or bill-of-materials documentation. Suitable for both OEM assembly and field maintenance replacement work.

Key Features

• M12 x 1.25 fine-pitch thread for increased vibration resistance versus standard coarse pitch
• Grade 8.8 steel construction provides high tensile and yield strength
• Fully threaded shank along the 30 mm length under head
• 19 mm hex drive compatible with standard metric sockets and wrenches
• Bright uncoated finish for bare-metal appearance and dimensional consistency
• Conforms to DIN 961 and ISO 8676 dimensional standards

Compatibility

Designed as an OEM-style replacement or maintenance fastener for metric-threaded assemblies specifying an M12 x 1.25 fine-pitch hex head cap screw per DIN 961 or ISO 8676.

Installation Notes

Installation is performed by qualified mechanics or maintenance technicians. Always confirm thread pitch with a pitch gauge before installation, as M12 x 1.25 fine pitch and M12 x 1.75 coarse pitch fasteners are not interchangeable. Follow equipment manufacturer torque specifications for Grade 8.8 M12 fasteners and use a calibrated torque wrench. Inspect mating threads for damage or contamination before assembly.
