Alloy Steel Long Length Socket Head Cap Screws
Long length alloy steel socket head cap screws pick up where standard catalog ranges leave off. Every diameter has a customary stopping point — the longest length most suppliers list — and this category holds what lies beyond it: the extra-long alloy steel socket head cap screws that machine builders, fixture designers, and maintenance shops reach for when a standard length simply won’t span the job.
The selection covers diameters from #0-80 through 3/4", with lengths running well beyond typical listings — many past a foot. These are the hard-to-find lengths: called for when through-bolting thick sections, clamping tall stacks, or reaching through housings and spacers where common sizes run out.
Cold Headers has been a master distributor of socket screws since 1962, and long lengths have always been part of the bench. Standard lengths for every diameter remain in our main Alloy Steel Socket Head Cap Screws listing — this category is the extension of each size range beyond it.
Pricing on long lengths varies with material and machining, so items here are quoted individually. Contact us with the size and quantity and we’ll respond promptly — and if a length you need isn’t shown, ask. The range published here reflects what we can supply, and it keeps growing as we continue putting our inventory online.
