Metric non-vented socket head cap screw DIN912, A4-70 SST Silver plated, M4x10mm

Socket Cap Screws – Precision Fastening to DIN 912 Standard

Our Socket Cap Screws, often called Allen head bolts, are engineered for strength and efficiency. Featuring a hexagonal recess, these screws are driven using a hex wrench or insert bit, offering superior resistance to cam-out compared to traditional slotted screws.

Why Choose Our Socket Cap Screws?

• DIN 912 Standard: Guaranteed precision and reliability.
• Hex Socket Drive: Provides secure fastening and higher torque capability.

Socket Head Cap Vented Screws – Designed for Vacuum Applications

For high-vacuum environments, we vent our screws using a coaxial hole through the center, the most effective method for maintaining fastener integrity while ensuring proper venting.

Precision Cleaning & Packaging

Every part is precision cleaned and Class 100 packaged for contamination-free performance. To reduce galling, we recommend using vacuum-stable lubricants such as Molybdenum Disulfide (MoS₂), Tungsten (WS₂), graphite, or silver plating.

Coated & Plated Options

Choose coated or plated screws for lower friction, resulting in higher tension or compression values at the same torque—ideal for demanding applications.
