• Low-profile, rounded button head design minimizes protrusion while providing a finished appearance
• Full regulatory compliance with RoHS 3 and REACH standards for safe, sustainable use

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M5 metric flange screws address critical challenges in assembly and maintenance. The 6061 aluminum construction offers an optimal strength-to-weight ratio, resisting corrosion in machinery, electronics, and outdoor equipment. The integrated flange design eliminates the need for separate washers, speeding up installation while distributing clamping force evenly to prevent material damage. With a fully threaded shank and coarse thread pitch, these button head screws provide rapid insertion and superior holding power in soft materials or vibration-prone settings, reducing maintenance intervals and improving operational reliability.

Specification Summary & Compliance

This flanged hex drive button head screw adheres to metric thread standards with M5 x 0.8mm coarse pitch and Class 6g thread fit for consistent dimensional accuracy. Manufacturing complies with RoHS 3 (2015/863/EU) under exemption 6(b)-II and REACH (EC 1907/2006) regulations, ensuring environmental safety. The Rockwell B40 hardness and 40,000 PSI tensile strength validate its durability for precision engineering applications.
