Outstanding advantages of expansion bolts (expansion anchors) Stainless steel 201
Good load-bearing capacity : Stainless steel 201 expansion bolts have superior load-bearing capacity compared to 304 expansion bolts. With carbon and manganese components, the bolts have superior mechanical strength. This helps increase stability and safety for construction works.
Low cost : Stainless steel expansion bolts 201 have a reasonable price, a cost-saving choice for contractors and construction engineers. Compared to other types of expansion bolts, 201 expansion bolts have an affordable price but still ensure effective use. This helps save costs for construction projects while still achieving high quality.
Good corrosion resistance : Stainless steel 201 has good corrosion resistance, almost rust-free in high humidity applications. However, the rust resistance and chemical resistance of stainless steel 201 expansion bolts are not good. Because the chromium and nickel content in the composition is often low, it directly affects the anti-rust properties of the bolt.
Stainless steel 201 expansion bolt
Stainless steel 201 expansion bolts have a simple structure with a round body and an expansion bolt at the end, helping to create a firm grip when installed on the material surface. Thanks to this feature, expansion bolts are often used to install wall-mounted equipment, scaffolding systems, or in outdoor works. In addition, the durability of stainless steel 201 expansion bolts is highly appreciated. They have the ability to withstand large loads without deformation.
3-wing expansion bolt Inox 201
201 Stainless Steel 3-wing expansion bolts stand out with a unique design consisting of three wings at the end, helping to increase the contact area with the surface and improve the load-bearing capacity. When tightened, the wings of the bolt will expand and adhere to the material. Although it does not have outstanding corrosion resistance, if used in indoor constructions, this is the most suitable type of expansion bolt. Because they are durable, can withstand large weights and impacts.
Hook expansion bolts made from 201 stainless steel
Finally, we have the 201 stainless steel hook expansion bolt. In terms of structure, they are not much different from the above bolts. But they will be equipped with an additional hook head used to fix suspension systems. 201 stainless steel hook expansion bolts usually have a large diameter so they can withstand loads of up to 700 kg without deformation, very suitable for industrial or construction works.
One and common application of 201 stainless steel expansion plugs
Stainless steel 201 expansion bolts are considered an effective solution in many construction and industrial projects thanks to their flexibility and stable durability. However, with lower corrosion resistance than other types of stainless steel such as 304 or 316, this product is often used in indoor environments or areas that are not in direct contact with chemicals or high humidity. Applications of stainless steel 201 expansion bolts.
- Install wall mounts and interior shelving systems.
- Reinforce structural details inside the building such as stairs, railings or scaffolding systems.
- Installation of mechanical equipment in factories or warehouses.
- Secure machinery, tool racks, or piping systems that do not come into direct contact with corrosive chemicals.
- Used to fix decorative systems or lighting
Construction of 201 stainless steel expansion bolts:
Construction steps for 201 stainless steel expansion bolts – expansion anchors
- Step 1 : First you must drill a hole suitable for the size of the 201 stainless steel expansion bolt. Depth, hole diameter and hole diameter are the most important dimensions when drilling holes. So you need to use the appropriate measuring tools and drilling tools.
- Step 2: Clean the hole with a specialized tool.
- Step 3: Insert the 201 stainless steel expansion plug into the hole and adjust the nut to match the given design.
- Step 4: Nail and secure the bolts, this will secure the connection.
- Step 5: Check and readjust the expansion bolt as desired.
