Black, Self-Colour Steel Hex Socket Set M4 x 20mm Grub Screw

Introducing RS PRO socket set screws, the perfect solution for securely fastening objects together with precision and reliability. Designed with a hexagonal recess, these screws are easily driven using a hex wrench, or driver bit, ensuring a flush application with the top surface when required. Often referred to as 'grub' screws, they feature a 'plain cup point' end with a concave hollow, ideal for applications where the point’s contact with the surface is non-detrimental.
Crafted from grade 45H steel, these screws offer exceptional durability and strength, making them the most popular choice for a wide range of applications. Their self-colour finish is intended for internal use, providing a sleek and professional appearance. Conforming to DIN 916 specifications, RS PRO grub screws guarantee high-quality performance and reliability. Choose RS PRO for your fastening needs, where quality meets precision.
