Product Description

1/4"-20 x 3-1/2" coarse-thread hex bolt (commonly listed as 1/4" x 3-1/2" hex head, coarse/UNC 20 TPI) — offered in zinc-plated/galvanized steel and stainless (18‑8/316) finishes and sold individually. This standard hex-head bolt is manufactured to ASME/SAE dimensional standards for hex cap screws/hex bolts and is suitable for light- to medium-duty fastening where a 1/4" hex head and 3-1/2" grip length are required (automotive trim, furniture assembly, light framing, brackets). Typical supplier/catalog options show A307/Grade 2 (zinc/galvanized) and 18‑8 stainless variants; head and thread geometry match common replacement parts stocked by national retailers and fastener houses. Competitive local resale recommendation for Dayton, IA (single-piece retail): $0.49 each for a zinc‑plated coarse 1/4" x 3‑1/2" hex bolt (rounding slightly above big‑box per-piece pricing while remaining below specialty catalog single-piece stainless prices). Rationale: big‑box single-piece street prices cluster around $0.38–$0.48/ea for zinc-plated items, while specialty/distributor single-piece stainless or grade-specific bolts commonly list $0.56–$0.75/ea; $0.49 positions a walk-in single-piece sale as competitive locally while leaving margin above common wholesale pack/unit costs.
