![[Resin Products] Types of Materials, Overview, Data Documentation](https://image.www.ipros.com/public/product/image/d4b/2000197439/IPROS3826629624215951130.jpg?w=280&h=280)
I have summarized the types and overview of the materials used for resin screws.
I wonder what types of materials there are for resin (plastic) screws. I have compiled data on material properties such as tensile strength, heat resistance, and chemical resistance in a catalog. We have a large stock available, so please feel free to inquire.
While maintaining strength, you can reduce the size of the bolts!! This is a highly functional fastener that is very effective for space-saving and weight reduction.
┏━━━━━━━━━━━━━━━━━━━━━━━━━━ ■ High-Strength Stainless Fastener SUS304CUN □ A2-90・100 Tensile Strength 900N/mm²・1000N/mm² ┗━━━━━━━━━━━━━━━━━━━━━━━━━━ This is a pure domestically produced high-strength stainless fastener made from the next-generation stainless steel "SUS304CUN" developed by Daido Steel Co., Ltd. By changing the conventional A2-50 to A2-90, we can achieve overall weight reduction and miniaturization. By dropping the nominal size by two levels, a 70% reduction in weight and size is possible. Of course, we can provide bolts that are resistant to rust and magnetism... We can meet such requests!! ★ We also accept various technical consultations! It will be smoother if you mention "I saw it on Ipros." ━…━…━…━…━…━…━…━…━…━…━…━…━…━…━ Yura Sansho Co., Ltd.

By simply turning the screw manually, leveling can be easily achieved. The load cap at the tip of the screw has a tilt structure, allowing the cap to follow up to a 10° angle relative to the workpiece, so you can use it with confidence.
It has several times the hardness compared to general abrasives! A high-precision wheel with sharp cutting performance that is efficient and long-lasting.
We would like to introduce our "Diamond/cBN Wheels." In the world of machining, diamonds and cBN are referred to as super abrasives, possessing several times the hardness compared to conventional abrasives like SiC and WA. The sharp cutting edges of these super abrasives excel in cutting performance, offering high efficiency and long lifespan, and are used in high-precision grinding wheels that produce a high grinding ratio. Additionally, they effectively dissipate heat from the grinding point to the wheel side, helping to prevent thermal alteration of the workpiece surface. 【Features】 ■ High efficiency and long lifespan ■ Sharp cutting performance with high-precision wheels ■ Several times the hardness compared to conventional abrasives like SiC and WA ■ Effectively dissipates heat from the grinding point to the wheel side *For more details, please refer to the PDF document or feel free to contact us.
Perfect for crime prevention measures! It truly shines in enhancing security for license plates and window frames.
"Lapis" is an anti-theft screw that is perfect for security measures. Due to its bit structure that requires a one-way special tool for fastening, it cannot be removed after being fastened. It is useful for areas where you want to create a black box, such as license plates and window frames. 【Features】 ■ Prevents removal after screw fastening, enhancing security ■ Bit structure that requires a one-way special tool for fastening ■ Cannot be removed after fastening ■ Head shapes available are only truss head and flat head *For more details, please refer to the PDF document or feel free to contact us.
