Alloy Steel Large Diameter Socket Head Cap Screws
This category gathers the largest diameters in our alloy steel socket head cap screw line — 7/8-9, 1-8, 1 1/4-7, and 1 1/2-6 — in lengths that run from under an inch up through 12 inches. These are the sizes that anchor heavy equipment, large fixtures, and other big-bore assemblies where a standard cap screw isn't enough fastener.
Every size here carries the internal hex drive and head proportions the socket cap style is known for, scaled up into serious bar-stock territory. Where a price is shown, it is quoted per 100 pieces; sizes marked Call or Email are quoted individually — reach us either way and we'll turn the number around quickly.
If the diameter or length you need isn't listed, ask. Large sizes are a specialty of the house, and our hard-to-find fasteners service covers odd lengths and configurations beyond what appears on this page.
