Value Collection 815155PR M12x1.5 Hex Cap Screw Grade 8.8

Product Description

The VALUE COLLECTION 815155PR is a metric hex head cap screw designed for bolted assemblies requiring precise thread engagement and reliable clamping force. Manufactured from Grade 8.8 steel with a zinc-plated finish, this screw offers a balance of tensile strength and corrosion resistance suited to general mechanical and structural applications. The M12 x 1.50 thread profile with a 50 mm length under head and partial threading makes it appropriate for through-bolt and flanged joint applications where a smooth shank is needed. It conforms to DIN 960 and ISO 8765 standards. Installation requires a 19 mm hex tool. Mechanical assemblers, millwrights, and maintenance technicians are the primary users of this fastener.

This screw is commonly used in machinery assembly, structural steel connections, automotive fabrication, and general industrial maintenance where metric fasteners are specified. The partially threaded shank is particularly useful in lap joints and applications that require a bearing surface between clamped parts. It is suited to both original equipment assembly and field repair work where DIN or ISO metric standards are called out on engineering drawings.

Key Features

• Grade 8.8 steel construction providing high tensile and proof load strength for demanding bolted joints
• Zinc-plated finish for moderate corrosion resistance in indoor and light-exposure environments
• Partially threaded shank for precise clamping in lap joints and flanged connections
• Conforms to DIN 960 and ISO 8765 standards for interchangeability in metric-specified assemblies
• 19 mm hex drive compatible with standard metric wrenches and sockets
• M12 x 1.50 fine-pitch thread for improved thread engagement and vibration resistance compared to coarse pitch

Compatibility

Designed as a DIN 960 and ISO 8765 conforming replacement or service fastener for metric bolted assemblies specifying M12 x 1.50 partially threaded hex head cap screws in Grade 8.8 steel.

Installation Notes

Installation should be performed by qualified mechanical or maintenance technicians following applicable torque specifications from the original equipment manufacturer or engineering drawings, as no torque value is supplied with this fastener. Always verify thread class and engagement depth before final assembly. Use a calibrated torque wrench and appropriate 19 mm hex socket or open-end wrench. Inspect mating threads for damage or contamination before installation.
