316 stainless hex lag screws are available in 5/16" diameter and 9 TPI coarse threads. They are made from 304 (A2) stainless steel, which resists rust and ensures long-lasting performance in moist or outdoor conditions. These screws are easily installed with socket wrenches. They have a hex head, spaced threads, and a gimlet point. Stainless steel lag screws are used for joining beams, joists, and rafters in framing, attaching ledger boards to house framing for decks, securing stair stringers to the framing, fastening fence posts and rails, assembling heavy furniture, joining thick, solid wood components, attaching hardware like hinges, brackets, or handrails, and securing large timber trusses or structural elements. They are also commonly used for securing small-to-medium furniture or cabinets, hanging pictures, mirrors, or shelving on walls, and working with thin, soft materials like drywall or plywood.
