SS304-316 Corrosion-Resistant J-Bolt

Product Overview

The SS304/316 J Bolt is a uniquely shaped fastening component characterized by its “J” curve—designed to hook and secure objects to surfaces like concrete, steel, or wood. Crafted from food-grade and corrosion-resistant stainless steels (SS304/A2/1.4301 and SS316/A4/1.4401), this bolt is a staple in projects requiring strong, permanent anchoring. As a core product in our fastener range, we offer a size range of M4 to M36, with the flexibility to handle both standard and custom orders (per drawings or samples). Backed by 18 years of fastener sales experience, we ensure timely delivery (most orders fulfilled within 7 days) and consistent quality, supported by EN10204-3.1B certification. Whether for construction, HVAC, or marine use, the SS304/316 J Bolt delivers reliable performance in diverse environments.

Product Features

Corrosion-Resistant Materials:

SS304 (1.4301): Contains 18–20% Cr and 8–10.5% Ni, resisting rust in indoor, dry, or mild outdoor environments (e.g., residential HVAC mounts).

SS316 (1.4401): Adds 2–3% Mo, enhancing resistance to saltwater, chemicals, and high humidity—ideal for marine, coastal, or industrial settings.

Versatile Size Range: Covers thread sizes from M4 (small-scale applications like electrical boxes) to M36 (heavy-duty uses like bridge supports). Lengths are customizable, with standard options ranging from 10mm to 1000mm to fit different anchoring depths.

Smooth Surface Finishes: All J bolts feature a Bright&Clean finish, which not only improves aesthetics but also reduces debris buildup. For added protection, we offer passivation (to enhance corrosion resistance) and polishing (for food or pharmaceutical applications) upon request.

No MOQ & Fast Delivery: We accept orders as small as 10 pieces (perfect for repairs or prototypes) and maintain raw material stock for SS304/316. Most standard orders are produced and shipped within 7 days, while custom orders take 10–14 days.

OEM & Technical Support: Supports full OEM customization, including non-standard “J” curve angles, thread types (metric/imperial), and custom markings (brand logos). Our team provides dimensional drawings and application advice to ensure the bolt fits your specific anchoring needs.

Applications

The SS304/316 J Bolt’s hooking design and material versatility make it suitable for countless industries:

Construction & Building: Used to anchor wooden beams to concrete foundations, secure drywall tracks to steel studs, and mount HVAC ductwork. SS304 is preferred for indoor use (e.g., office buildings), while SS316 is used in outdoor structures (e.g., parking garages, coastal homes).

Marine & Coastal Infrastructure: Installed in boat docks (securing fenders), seawalls (anchoring reinforcing bars), and coastal piers (mounting safety rails). SS316’s resistance to saltwater corrosion prevents bolt failure in these high-moisture environments.

Electrical & Mechanical: Applied in electrical substations (mounting cable trays) and industrial machinery (securing guards or vibration dampeners). The “J” shape ensures a tight grip, even under mechanical vibration.

Agriculture & Food Processing: Used in food plants (mounting stainless steel conveyors) and agricultural facilities (securing grain silo components). SS304/316’s non-toxic, easy-to-clean properties comply with food safety standards (e.g., FDA).

FAQ

Q1: What’s the difference between SS304 and SS316 J Bolts—how do I choose?

A1: The key difference is molybdenum (Mo) content: SS316 has 2–3% Mo, while SS304 does not. Choose SS304 for dry, indoor, or mild outdoor environments (e.g., residential HVAC). Choose SS316 for saltwater (marinas), chemicals (industrial plants), or high-humidity areas (greenhouses) to prevent corrosion.

Q2: Can you produce J bolts with imperial threads (e.g., 1/4”, 3/8”)?

A2: Yes. We offer both metric (M4–M36) and imperial (1/4”–1 1/2”) threads. Simply specify the thread size, pitch, and length in your order, and we’ll produce them to match ANSI/ASME standards for imperial sizes.

Q3: What’s the maximum load capacity of the SS316 M12 J Bolt?

A3: The load capacity depends on the bolt length and anchoring material, but for an M12 SS316 J Bolt (length 100mm) anchored in concrete, the ultimate tensile load is approximately 80kN (8,000kg). We can provide detailed load charts for specific sizes upon request.

Q4: Do you offer packaging for international shipping?

A4: Yes. For international orders, we use seaworthy packaging: bolts are bulk-packed in anti-rust plastic bags, placed in cardboard boxes, and stacked on wooden pallets (heat-treated to ISPM 15 standards) to prevent damage from moisture or rough handling.

Q5: How long does it take to receive a custom J bolt sample?

A5: Custom samples (e.g., non-standard curve or thread) typically take 5–7 business days to produce and ship. We’ll send a digital drawing for your approval first, and once confirmed, we’ll manufacture the sample and include a material test report (MTR) for verification.
