As a professional set screw manufacturer, JHLY specializes in producing high quality set screws for industrial customers, OEM manufacturers, distributors, and engineering companies worldwide. With strict quality control, advanced manufacturing processes, and extensive experience in precision fasteners, JHLY provides dependable set screw solutions that meet the requirements of various industries, including machinery, automation, automotive, electrical equipment, and precision instruments.
JHLY set screws are designed to provide secure positioning and reliable locking performance in mechanical assemblies. Unlike traditional bolts and screws, set screws are installed directly into threaded holes and apply pressure against a shaft or component to prevent movement. This makes them an essential fastening solution for applications such as gear fixing, shaft locking, pulley assembly, motor components, and industrial equipment. Customers choose JHLY set screws because they require consistent quality, accurate dimensions, excellent mechanical performance, and reliable supply capability.
To meet different application requirements, JHLY manufactures a wide range of set screw types, including cup point set screws, flat point set screws, cone point set screws, and dog point set screws. Among them, cup point set screws are one of the most commonly used designs because the concave tip provides strong gripping force and effective resistance against loosening. Flat point set screws are suitable for applications where surface protection and repeated adjustment are required, while cone point and dog point set screws are often selected for applications requiring stronger positioning and higher locking performance.
Material selection is an important factor in determining set screw performance. JHLY offers set screws in various materials, including stainless steel, alloy steel, and carbon steel, allowing customers to select the most suitable solution according to their working environment. Stainless steel set screws, such as SUS304 (A2) and SUS316 (A4), are widely used in applications where corrosion resistance is required, including food processing equipment, marine systems, outdoor machinery, and chemical environments. Alloy steel set screws provide higher strength and wear resistance after heat treatment, making them suitable for heavy machinery, automotive components, and high-load applications. Carbon steel set screws offer a cost-effective solution for general industrial fastening applications where standard mechanical performance is required.
In addition to different materials, JHLY provides a variety of surface finishes and coatings to improve corrosion resistance, appearance, and service life. Common finishes include black oxide, zinc plating, zinc flake coating, and stainless steel passivation treatment. Black oxide set screws are widely used in general machinery applications because of their clean appearance and basic corrosion protection. Zinc-plated set screws provide economical corrosion resistance and are commonly used in industrial equipment. For more demanding environments, zinc flake coatings offer enhanced corrosion protection and improved durability, making them suitable for automotive and outdoor applications. Stainless steel passivation further improves corrosion resistance by creating a cleaner and more stable surface condition.
JHLY manufactures set screws according to internationally recognized standards, including DIN, ISO, and ANSI requirements. Common specifications include DIN 916 hexagon socket set screws with cup point, DIN 913 flat point set screws, DIN 914 cone point set screws, and ISO 4026, ISO 4027, ISO 4028, and ISO 4029 standards. By following international standards and maintaining strict inspection procedures, JHLY ensures that every batch of set screws delivers consistent quality and reliable performance for global customers.
Besides standard set screws, JHLY also specializes in customized set screw manufacturing services. We understand that many industrial applications require specific dimensions, materials, coatings, or packaging solutions. Our engineering team works closely with customers to provide OEM set screws, customized sizes, special thread specifications, and application-specific fastening solutions. Whether customers need metric or inch sizes, small precision components, or large-volume production orders, JHLY can provide flexible manufacturing support.
As a trusted set screw supplier, JHLY serves customers across different industries and markets by combining competitive factory pricing, reliable quality, professional communication, and strong production capability. Our goal is not only to supply fasteners but also to become a long-term manufacturing partner for companies looking for stable and high-quality fastening solutions.
