M6 M8 M10 Hexagon Hex Socket Button Head METAL Screw Assembled With Washer 304 316 316L

This SEMS screw range integrates three popular head styles – hexagon head, hex socket head, and button head – with pre-assembled flat or spring washers that are captive on the thread. Manufactured from high‑quality stainless steel including SS304, SS316, SS316L, as well as AISI, SUS and ANSI equivalents, these fasteners offer excellent corrosion resistance. The button head provides a low‑profile appearance, the hex head accepts standard wrenches, and the socket head allows high torque in confined spaces. The washer is permanently retained, preventing loss or misplacement on assembly lines. With a natural (plain) finish, the screws rely on the stainless steel’s passive oxide layer for protection. Available in M6, M8 and M10, they are ideal for general machinery and equipment assembly.

• Food processing equipment: SS316L resists chlorides from cleaning agents.

• Medical instruments and lab devices: SS304 offers hygiene and good formability.

• Outdoor solar panel frames: SS316 provides long‑term coastal corrosion resistance.

• General mechanical assembly: hex head SEMS screws for pumps, motors, conveyors.

• Automation tooling: socket button head screws for low‑clearance areas.

• Captive washer design eliminates washer loss, boosting assembly efficiency.

• Three drive options suit different torque and access requirements.

• Choice of stainless grades allows matching corrosion resistance to the environment.

• Full or partial thread available to optimise clamp length.

• Multi‑standard compliance (DIN, ISO, ANSI, JIS) simplifies global sourcing.
