Value Collection 535198PR M12x1.75 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535198PR is a fully threaded button socket cap screw manufactured from alloy steel with a black oxide finish. It features an M12x1.75 metric thread and a 35 mm length under head, with an 8 mm hex socket drive. The black oxide coating provides mild corrosion resistance and reduces light reflection. At a material grade of 12.9 and a hardness range of 38-43 HRC, this fastener delivers high tensile strength suited for demanding mechanical assemblies. Installation requires a standard hex socket driver or Allen key. This screw conforms to ANSI/ASME B18.3.4M and ISO 7380 standards, making it a reliable choice for precision and industrial fastening applications.

This button socket cap screw is used in mechanical assemblies where a low-profile head is required and a flush or recessed finish is preferred. The metric M12x1.75 thread size and 12.9 grade alloy steel construction make it appropriate for high-load structural and machine component applications. It is commonly installed by machinists, millwrights, and maintenance technicians working on equipment frames, brackets, guards, and similar assemblies in industrial and manufacturing environments.

Key Features

• M12x1.75 fully threaded metric thread with right-hand thread direction
• 35 mm length under head provides consistent grip range for standard flange and plate applications
• Alloy steel at material grade 12.9 with hardness of 38-43 HRC for high tensile strength
• Black oxide finish for mild corrosion resistance and low-glare appearance
• 8 mm hex socket drive for use with standard Allen keys and socket drivers
• Conforms to ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as an ISO 7380-compliant button socket cap screw for metric M12x1.75 threaded applications requiring a low-profile head. Thread fit classes 4G and 6G apply per standard metric tolerancing.

Installation Notes

Installation should be performed by a qualified technician familiar with metric fastener torque specifications and assembly procedures. Ensure the mating threaded bore or nut is clean and free of debris before driving the screw. Use a calibrated torque tool appropriate for grade 12.9 fasteners and follow the equipment manufacturer's torque specifications, as none are provided with this part. Avoid impact drivers that may exceed rated torque and damage the hex socket or thread engagement.
