Silver 6061 Aluminum Flange Two Hole Alignment Pin 1-1/8" 1-5/8" 4 Pc Set
Silver 6061 Aluminum Flange Two Hole Alignment Pin 1-1/8" 1-5/8" 4 Pc Set
When bolt-hole misalignment brings your pipe fitting or mechanical assembly job to a halt, these Silver 6061 Aluminum Flange Two Hole Alignment Pins get you back on track — fast. Precision-machined from 6061 aerospace-grade aluminum with a natural silver finish, this set includes 1-1/8" pins for 3/8" to 1" bolt holes and 1-5/8" pins for 1/2" to 1-1/2" bolt holes on flanges up to 3" thick. At approximately 30% lighter than stainless steel alternatives, the lightweight aluminum construction reduces hand fatigue during overhead and extended pipe fitting work while providing the same corrosion resistance professionals demand. The detachable thread design means no special tools, wrenches, or power equipment are required — simply hand-tighten and start aligning. Engineered with tight machining tolerances, the dual-hole configuration eliminates bolt-hole misalignment during assembly, allowing bolts to slide through smoothly the first time and preventing stripped threads or costly rework. The natural silver aluminum finish also means the surface won't mar or scratch mating flange faces — a common concern with harder steel pins. Suitable for professionals and workshop operators alike: use them for pipe flange alignment in plumbing and HVAC systems, mechanical coupling assembly in manufacturing, automotive exhaust and chassis work, or general industrial equipment maintenance. Compact enough to carry in a toolbox and simple to position single-handedly, this alignment pin set replaces multiple specialty tools in one portable package.
