Set Screw Fasteners
When locking pulleys, gears, collars, and shafts in place without a protruding bolt head, our high-precision Set screw fasteners are the optimal choice. Designed with an internal hex socket drive that sits completely flush with or below the surface of the component, these screws apply reliable compressive force through the point to prevent axial or rotational movement between assembly parts.

Designed with an internal hex socket drive that sits completely flush with or below the surface of the component, these screws apply reliable compressive force through the point to prevent axial or rotational movement between assembly parts. We manufacture our Set screw fasteners from premium-grade alloy steels and stainless steel, ensuring they can withstand high tightening torques and resist stripping. Each screw is precisely threaded and finished with a variety of contact points-including cup points, cone points, dog points, and flat points-to match the hardness of your mating shaft and deliver maximum slip resistance in electric motors, power tools, and high-speed industrial machinery.
Shanghai Megood Metal Products Co., Ltd. has specialized in the development and production of precision fasteners since 2006. Located in Waigang Town, Jiading District, our 2,200-square-meter facility features advanced automatic high-speed thread rollers, cold-headers, and CNC machines. Our Set screw fasteners are manufactured under strict compliance with ISO 9001 and IATF 16949 quality guidelines, utilizing advanced optical sorting systems to ensure zero thread defects and perfect drive dimensions. We strictly respect environmental conservation, employing RoHS-compliant surface finishes including non-hazardous trivalent black zinc plating and advanced chemical passivates. For global distributors and OEM purchasing managers, our direct-factory model guarantees stable, reliable supply chains, consistent dimensional tolerances, and dedicated customer service representatives who assist you through every phase of order fulfillment.

Customization Capabilities
We provide customized OEM and ODM engineering, allowing us to manufacture non-standard Set screw fasteners with customized point geometries, unique thread pitches, or custom lengths tailored to your exact application. Tooling design and sample creation typically require one month. Free standard samples are available from our warehouse inventory. For standard cold-headed set screws, our MOQ is 50,000 pieces, whereas specialized low-volume runs on CNC lathes are evaluated individually.
Packaging & Shipping
We package our set screws in bulk inside heavy-duty plastic bags to prevent friction-induced thread wear, which are then boxed and placed into master shipping cartons. Cartons are stacked on export wooden pallets and wrapped securely in protective shrink film. We ship under EXW and FOB Shanghai terms, accepting USD payment through standard international banking channels.
Why Our R&D and Fast Delivery Help You
We have our own R&D team. You can share your special needs. We will help solve your technical problems. Free samples are ready for stock items. Mass production takes 2-3 weeks for standard parts. Custom products take 4 weeks. Repeat orders are even faster. The elongation rate for 65MN is ≥10%. So the washer will not crack during installation. It works with regular bolts, high-strength bolts, and stainless steel bolts. You do not need to change your tools.
The entire product line is fully customizable.
FAQ
Q: Which set screw point style should I use for my shaft assembly?
A: The cup point is the most common, ideal for quick installation on soft shafts where minor scarring is acceptable. If you need a permanent lock without damaging the shaft, a flat point or a specialized brass-tipped set screw is recommended. For pre-drilled shaft grooves, a dog point provides maximum shear resistance.
Q: How do you prevent hex socket stripping under high tightening torques?
A: We utilize premium high-carbon alloy steel (such as SCM435) combined with controlled induction hardening. This ensures that the internal hex socket walls remain highly resistant to deformation, allowing you to achieve maximum holding power without driver slippage.
Q: What is your typical production turnaround time for repeat orders?
A: For established repeat orders with approved specifications, our factory can streamline production, delivering the finished batch within 2 weeks.
