Hex Socket Head Cap Screws

The hex socket head cap screws has a hexagonal groove on the top, is corrosion-resistant, easy to install, and can withstand higher loads than ordinary screws. It can be used in machinery, electronic equipment, transportation, furniture and many other places.

Hex socket head cap screws follow standards like ISO 4762 for metric sizes or ASME B18.3 for imperial ones. Their diameters go from M1.6 up to M64, and lengths can be as long as 300mm. Threads can be coarse (for everyday use) or fine (for precise adjustments). If you need custom screws, you can get non-standard lengths, special shoulder designs, or drives that prevent tampering. We have detailed tech charts that list torque limits, shear strength, and which parts they work with. Always check the sizes against your project’s blueprints to make sure the screws fit your exact needs.

Features

Hex socket head cap screws get coatings to make them last. Zinc plating fights rust, hot-dip galvanizing (dipped in zinc) holds up better outside, and Dacromet handles high heat. Black oxide reduces glare and looks cleaner while adding a little rust protection. For food factories or chemical-heavy spots, passivated screws fight rust and won’t leave nasty stuff behind. Coatings such as PTFE or Xylan allow components to glide more smoothly, reducing friction between moving parts.Basically, pick the coating based on where the screw’s going,it’ll keep things running smoother in whatever job you throw at it.

product packaging

We use simple and practical packaging for this screw, mainly to protect it during transportation and storage. The common packaging is plastic bags, with each bag containing a fixed number of screws, usually 100 pieces or 500 pieces, depending on the size. Each bag is labeled with basic information, including the screw size, thread specification, and quantity. For bulk orders, we put the plastic bags into cartons. The cartons are sturdy enough to prevent the screws from being crushed or deformed during transportation. We also add a layer of foam or paper inside the cartons to reduce collision between the screws. The packaging doesn’t have any fancy designs, just focuses on practicality. It’s easy to open, and you can take out the screws you need without wasting time. The packaging also helps keep the screws organized, so you don’t have to sort them out when using. Hex Socket Head Cap Screws is packed in a way that is convenient for storage, transportation and daily use, meeting the needs of factories and individual users.

Quality standards

Q:Are hex socket head cap screws compliant with international standards like ISO or DIN?

A:Hex socket head cap screws stick to global standards like ISO 4762 (metric) or DIN 912 (imperial). These rules basically make sure the screws are the right size and they’ll work consistently. Following them also means they’ll fit with tools and parts everyone uses. For certain jobs,like cars (ISO/TS 16949) or boat stuff (ASTM F593),there are extra certifications that cover things like rust-proofing or where the metal’s sourced from. When picking these screws, just check what standard your project needs (like ASME B18.3 in the U.S.) to match local regulations or your project’s specs. Keep it simple: standards = no surprises.
