RS PRO Steel Grub Screw, Plain Cup Point, M4 Thread, 12 mm Length, DIN 916, Black, 529-955

RS PRO 529-955 Steel Grub Screw is a specialized fastener designed for precision mechanical applications. Featuring a metric M4 thread size and 12 mm length, this grub screw is manufactured from robust steel and has a black finish for added corrosion resistance. The plain cup point is the most widely used tip style, engineered for secure holding without permanent deformation of the mating surface.

This type of fastener, commonly referred to as a 'headless' or 'blind' screw, is ideal for installations where a flush fit in confined locations is necessary. The hexagon socket allows reliable tightening and release with an Allen key. DIN 916 compliance ensures consistent quality and technical standards for hex socket set screws with cup point. The grade 14.9 steel construction delivers high tensile strength for demanding industrial, laboratory, and electronic applications.

Typical uses include fixing components within machinery, securing assemblies in industrial tools, maintaining electronic enclosures, and automotive repairs. The M4 thread facilitates compatibility with metric sockets and hardware, while the 12 mm length is optimal for medium-depth anchoring. Its black color aids in identification and offers a professional, industrial aesthetic.

The grub screw's no-head design makes it perfect for use in locations where minimal protrusion is critical for safety and operational efficiency. The cup point ensures a balanced grip, suitable for parts requiring non-permanent fixation and frequent adjustment.
