DIYers, makers, and tradespeople who work with suspended loads, cable routing, or tie-down anchors need eyelet screws that hold their rated load without corroding, seizing, or deforming over time. These 304 stainless steel ring screws are built for exactly that kind of repeated, load-bearing use.\u003c\/p\u003e\n\u003cp\u003eEach lifting bolt is machined from 304-grade stainless steel and features a fully closed circular ring head with a standard metric threaded shank. The range spans M3 through M30 (approximately 0.12 in to 1.18 in thread diameter), covering light-duty cable management at the small end and structural rigging anchors at the large end. Available in packs of 1, 3, 5, 10, or 20 pieces to match project scale.\u003c\/p\u003e\n\u003cp\u003eTypical applications include workshop ceiling cable runs, tent and canopy anchor points, marine deck hardware, PC case wire management loops, and load-bearing suspension rigs for photography or stage lighting. The closed-ring geometry makes these eyelet screws compatible with carabiners, S-hooks, shackles, and wire rope thimbles — a versatile fastener for any rigging-adjacent build.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Standard metric thread pitch (coarse).
