FASTENER KIT 150# 3.5" & 4", 300# 2"- ZI

Zinc-Plated ASTM A193 Grade B7 Stud and Hex Nut Fastener Kit, 3.5 and 4 in, 150 lb pressure class is a zinc-plated flange bolting kit for gasketed pipe flange connections in industrial maintenance and installation work. The ASTM A193 Grade B7 bolting specification supports durable service where consistent clamping force is needed to compress gaskets and help maintain leak-resistant joints. This kit is sized for 3.5 and 4 inch 150 lb pressure class and 2 inch 300 lb pressure class flange applications and includes 8 ASTM A193 Grade B7 studs (0.625 in diameter x 3.5 in length) with 16 0.625 in heavy hex nuts. It helps buyers, distributors, and maintenance teams source compatible studs, capscrews, and heavy hex nuts as a matched set instead of assembling separate pieces. Use it for pipe flanges, process piping, equipment nozzles, valve connections, and general plant MRO where reliable industrial flange fasteners are required. Buyers may compare this item with flange fastener kits, B7 stud and nut kits, zinc plated fasteners, pipe flange bolting kits, and industrial flange fastener sets. The EA unit of measure supports clear ordering and reseller catalog setup, while the detailed hardware dimensions help reduce selection errors during replacement planning, turnarounds, and routine maintenance. When matched with the correct gasket, flange rating, and installation procedure, this kit supports dependable bolted joint assembly.
