### ⭐⭐⭐⭐⭐ High-Quality Screws and Great to Keep as Workshop Spares
*by G***D on May 12, 2026*

I purchased these screws primarily for my marble clock project, but they have also become a very useful addition to my workshop inventory. The dimensions were accurate, the black finish looks great, and the screws feel strong and well made. The 12.9 grade alloy steel provides excellent strength and gives confidence that they will hold up well in demanding applications. Having a large quantity on hand is extremely convenient. Fasteners are one of those items that always seem to be needed unexpectedly, and keeping a supply in stock saves both time and frustration. If you need high-quality M4 socket head cap screws, these are an excellent choice and offer outstanding value for the quantity provided.
