Value Collection 535008PR M3x0.5 Button Socket Cap Screw

Product Description

The VALUE COLLECTION 535008PR is a button socket cap screw designed for metric fastening applications where a low-profile head and high clamping strength are required. Manufactured from alloy steel with a black oxide finish, this screw meets ISO 7380 and ANSI/ASME B18.3.4M standards. It features an M3x0.5 thread and a 10 mm length under the head, driven by a 2 mm hex socket. The material grade of 12.9 and a hardness rating of 38 to 43 HRC make this fastener suitable for demanding, high-stress assemblies. It is fully threaded with a right-hand thread direction and falls within thread fit class 4G and 6G tolerances.

This screw is well suited for machinery, tooling, fixtures, and precision mechanical assemblies where a flush or low-profile fastener head is needed to clear adjacent components. The black oxide coating provides mild corrosion resistance and reduces surface reflectivity, making it a practical choice in industrial and manufacturing environments. It is sold individually, with a minimum order quantity of 100 pieces, making it appropriate for production or maintenance stock purchasing.

Key Features

• Button head profile keeps fastener below or flush with surrounding surfaces
• Grade 12.9 alloy steel provides high tensile strength for demanding assemblies
• Hardness of 38 to 43 HRC supports resistance to wear and deformation
• Black oxide finish offers mild corrosion resistance and low reflectivity
• Complies with ISO 7380 and ANSI/ASME B18.3.4M fastener standards
• Fully threaded with right-hand M3x0.5 metric thread

Compatibility

Designed as an OEM-style replacement or production fastener for metric threaded assemblies requiring an ISO 7380 button socket cap screw in M3x0.5 thread size.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or mechanical assemblers using a 2 mm hex socket driver or Allen key. Ensure mating threads are clean and free of debris before installation. Do not exceed recommended torque limits for grade 12.9 fasteners as specified by applicable engineering standards. Follow all relevant workplace and equipment safety procedures when working with high-strength fasteners in pressurized or load-bearing assemblies.
