Professional Applications & Engineering Value
This M4 thumb screw combines the lightweight durability of a powder-coated aluminum head with the robust performance of 400 Series Stainless Steel threads, creating an ideal solution for repeated access panels in electronics, instrumentation, and industrial equipment. The knurled texture ensures secure grip even with gloved hands, while the coarse metric thread (M4x0.7) provides rapid installation and vibration resistance. Engineered specifically for 6.4mm panel holes and 1-1.6mm panel thickness, it eliminates loose hardware in applications requiring frequent maintenance. The black powder-coated finish offers both aesthetic consistency and additional corrosion protection, making these captive panel screws suitable for OEM production lines and field service applications where reliability and ease of use are critical.
Specification Summary & Compliance
This metric thumb screw features standard M4x0.7 coarse threads with right-hand thread direction and ISO-compliant dimensions. The assembly combines a powder-coated aluminum head (13mm diameter, 11.3mm height) with 400 Series Stainless Steel threaded body (8.8mm length). Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and electronic applications requiring restricted substance control.
