SHOP ONLINEA2 stainless steel metric socket head cap screws are corrosion-resistant fasteners designed for machinery, equipment, marine hardware, and industrial assemblies where a standard external hex head may not fit. These A2 stainless socket screws use an internal hex drive, so installers can tighten them with a metric Allen key in tight or recessed spaces.
Marsh Fasteners supplies A2 stainless steel metric socket head cap screws in several styles, including standard socket head cap screws, flat head socket cap screws, button head socket cap screws, and cup point socket set screws.
These metric cap screw stainless steel options are a strong fit for clean assemblies, precision equipment, and projects that need reliable corrosion resistance in most indoor, outdoor, and moderately corrosive environments.
Our Range of A2 Stainless Steel Metric Socket Head Cap Screws Includes
A2 stainless metric socket screws come in several head styles. The right choice depends on clearance, finish, clamping force, and how the fastener will be accessed during installation or service.
Metric Socket Head Cap Screws
Metric socket head cap screws are internal hex-drive fasteners used where strong tightening and limited-space installation are required. The cylindrical head provides a large bearing surface and allows higher clamping force than many low-profile styles.
These DIN 912 A2 stainless screws are commonly used in:
Allen cap machine screws are useful when the head must fit inside a counterbore or when side clearance is limited.

Metric Flat Head Socket Cap Screws
Metric flat head socket cap screws are countersunk socket screws designed to sit flush with the surface after installation. They are used where a raised fastener head would interfere with movement, fit, or appearance.
These DIN 7991 A2 screws work well for:
Flush socket screws are a good choice when the fastener should not protrude above the surface.
Metric Button Head Socket Cap Screws
Metric button head socket cap screws have a rounded, low-profile head with an internal hex drive. They are often used where the head remains visible and a cleaner finished look is preferred.
These DIN 7380 A2 fasteners are suited for:
Allen button screws provide a smooth head profile while still allowing internal hex drive installation. Round head socket screws are not the best option for maximum clamping force, but they work well when clearance and finish matter.

Metric Cup Point Socket Set Screws
Metric cup point socket set screws are headless socket screws used to secure parts without a raised head. They are often called grub screws. These DIN 916 A2 screws use a cup point that bites into the mating surface to help hold components in place.
Common uses include:
Headless socket screws are useful when the fastener must sit flush inside a threaded hole.

Choosing Metric Socket Cap Screws for Your Project
Choosing metric socket cap screws starts with the assembly drawing, tapped hole, nut size, and installation environment.
Review these factors before ordering:
The A2-70 vs. A2-80 selection should come from the load requirement, project specification, or equipment drawing. Do not substitute strength classes without checking the design requirements.
