Quantity
Introducing our high-performance SS316 Bolts and Nuts, precision-engineered in Quanzhou to deliver superior fastening solutions for demanding industrial environments. This matched set comprises a heavy-duty stud bolt and a corresponding heavy hex nut, crafted from premium-grade 316 stainless steel. With a nominal size of 3/4 inch and a 10 UNC (Unified Coarse) thread series, this fastener combination provides robust clamping force and ease of installation. The bolt features a total length of 4.5 inches, offering ample engagement length for a secure and vibration-resistant joint. Manufactured and tested strictly in accordance with ASME B18.31.2 (for stud bolts) and ASME B18.2.2 (for heavy hex nuts), our SS316 Bolts and Nuts guarantee dimensional accuracy, mechanical integrity, and interchangeability with other standard components.
Superior Material & Corrosion Resistance
The defining feature of these fasteners is their SS316 austenitic stainless steel composition. Unlike standard 304 grade, SS316 contains molybdenum (2-3%), which significantly enhances resistance to pitting and crevice corrosion, particularly in chloride-rich environments such as seawater, de-icing salts, and chemical processing streams. This makes our SS316 Bolts and Nuts exceptionally durable against rust, oxidation, and stress corrosion cracking, even at elevated temperatures. The 10 UNC threading ensures smooth torque application and reduces the risk of galling, a common issue with stainless steel fasteners, while the 4.5-inch overall length provides versatility for flange connections, pressure vessels, and structural joints.

Key Applications and Use Cases
Our SS316 Bolts and Nuts are the go-to choice for mission-critical applications across multiple sectors:
- Marine and Offshore Engineering: Ideal for shipbuilding, dock structures, oil rig platforms, and subsea equipment where continuous saltwater exposure is a concern.
- Chemical and Petrochemical Plants: Suitable for piping flanges, pump casings, valve assemblies, and reactor vessels handling corrosive acids, alkalis, and organic solvents.
- Food Processing and Pharmaceutical Industries: Compliant with sanitary requirements, these fasteners resist contamination and are easy to clean in washdown environments.
- Water Treatment and Desalination Plants: Excellent performance in reverse osmosis systems, chlorination tanks, and wastewater treatment facilities.
- General Construction and Infrastructure: Reliable for bridge bolting, exterior cladding, and coastal building projects requiring long-term weather resistance.

Quality Assurance and Standards Compliance
Every batch of our SS316 Bolts and Nuts undergoes rigorous dimensional inspection, tensile testing, and hardness verification to meet ASME B18.31.2 and B18.2.2 specifications. The 10 UNC threads are carefully rolled to achieve precise pitch diameter and smooth flank surfaces, ensuring consistent preload and fatigue resistance. We also offer optional coatings (such as PTFE or silver plating) upon request to further prevent thread galling and enhance lubricity during high-temperature assembly.
