Key benefits Corrosionresistant stainless steel construction (304 and 316 options) for longlasting performance in wet, humid, or outdoor environments. Standard hexagon (hex) full nut design provides reliable clamping and easy installation with common wrenches and sockets. Multiple sizes and standard threading ensure compatibility with a wide range of bolts, fasteners, and assemblies. Sold in convenient pack quantities for immediate use (see variant: 316 Stainless Steel,3I 816 10pcs). What this product is and why you need it These are precisionthreaded hexagon (hex) full nuts made from quality stainless steel (304 and 316). They secure bolts and studs in mechanical assemblies, construction projects, and work where corrosion resistance and dependable fastening are required. If you need a durable, standardized nut that fits common wrench sizes and maintains strength in aggressive environments, these stainless steel hex nuts are a practical choice. Key attributes Material: 304 Stainless Steel and 316 Stainless Steel options (corrosionresistant, suitable for general and more corrosive environments respectively). Shape: Hexagon (6sided) full nuts for solid bearing surface and easy tool access. Threaded: Standard internal threading designed to match corresponding bolt sizes and threads. Sizes available (as listed): 0# 2# 12# 1/2 1/4 3/4 3/8 5/16 5/8 7/16 1' Package example: (316 Stainless Steel,3I 816 10pcs) — 10 pieces in this specific variant. Functionality: Tightening, locking, and clamping in assemblies where steady torque and load distribution are needed. How it solves common problems Prevents loosening and improves assembly reliability when paired with the correct bolt or stud. Resists rust and pitting that can cause fastener failure, extending service life in outdoor, marine, and industrial settings. Standard hex shape reduces installation time and simplifies maintenance with standard hand and power tools. Compatibility and performance Designed to mate with matching threaded bolts or studs of the same nominal size and thread pitch. Works with common wrench and socket sizes for quick installation and removal. 316 stainless option offers enhanced resistance to chloride and salt environments compared with 304 stainless. Typical use cases Marine and coastal equipment: fasten fittings, brackets, and hardware exposed to salt water where 316 stainless offers corrosion resistance. Machinery and equipment assembly: secure shafts, housings, and components that require strong, standardized fastening. Plumbing, HVAC, and outdoor construction: durable fastening for fixtures, supports, and structural connections where moisture or outdoor exposure is a concern. What's included Hexagon full nuts in the sizes listed above. Specific listing variant example: 316 Stainless Steel,3I 816 10pcs (10 pieces of the specified size and material). Notes for selection Match the nut size and thread pitch to your bolt or stud for proper fit and torque performance. Choose 316 stainless steel for harsher or saltwater environments; 304 is suitable for generalpurpose and less aggressive conditions. Precautions Ensure the nut size and thread specification match the mating fastener before installation. Use appropriate torque based on bolt grade and application; overtorquing can damage threads even on stainless steel fasteners.
