Full Product Description

The Professional Solution for Precision Fastening

In mechanical assembly and electronic repairs, stability is everything. Our 240pcs Hexagon Socket Set Screw Kit (commonly known as Grub Screws) is designed to provide a flush, headless finish that locks components into place without protruding parts. Whether you are securing a door handle, fixing a 3D printer, or maintaining CCTV mounting brackets, these screws offer the reliability you need.

Why Choose 304 Stainless Steel?

Environment matters. In high-humidity regions like Hong Kong, standard steel fasteners often succumb to rust. These screws are forged from Grade 304 Stainless Steel, ensuring they remain rust-free and structurally sound even in challenging environments. The concave end (cup point) design allows the screw to bite into the mating surface, providing high resistance to vibration and loosening over time.

Organized, Labeled, and Ready to Work

No more digging through messy toolboxes. This kit comes in a transparent, high-impact plastic organizer with dedicated compartments for each size. We have also included 5 matching Allen wrenches, ensuring you have the exact tool needed for every M3, M4, M5, M6, and M8 screw in the box. It’s a "grab-and-go" solution for engineers, hobbyists, and maintenance professionals alike.
