Hex Socket Head Cap Screw Keno M8×25 K-18-25 — Stainless/Steel size M8 length 25 mm

Keno hex socket head cap screw M8×25 (model K-18-25) is a metric M8 fastener with a 25 mm threaded length designed for assembly and mechanical fastening. The screw features an internal hex drive that accepts an Allen key, enabling controlled torque application and secure, flush fastening in machinery, furniture and metal structures. Constructed from stainless steel, it resists corrosion and suits both indoor and outdoor applications where a compact head and reliable clamping are required.

Advantages

The internal hex drive provides accurate torque transfer and reduces the risk of cam-out compared with slotted or Phillips heads. The compact cylindrical head allows installation in confined spaces and gives a neat, low-profile finish. Stainless steel construction offers good corrosion resistance and dimensional stability under normal environmental conditions. The metric M8×25 dimensions are a common standard for mechanical assemblies, simplifying parts selection and interchangeability.

Suitable for

• Mechanical assemblies and machine maintenance
• Furniture construction and fittings
• Metal framework and structural fastening
• DIY projects and repair work

Key specifications

• Thread size: M8
• Threaded length: 25 mm
• Head type: hex socket cap (internal hex / Allen drive)
• Material: stainless steel
• Drive: internal hex compatible with standard Allen keys
• Finish: natural stainless steel surface

How to use

Select an Allen key that fits the internal hex snugly to avoid rounding the drive. Position the screw into the pre-drilled or tapped hole and apply steady torque until the head is flush with or slightly below the mating surface, according to assembly requirements. For through-bolt connections, pair the screw with an appropriate nut and washer; for threaded holes, ensure the mating thread pitch and class match the M8 specification. Do not exceed recommended torque values for the material and application to prevent thread stripping or head damage.

Usage recommendations

For best results, use a torque-controlled driver when assembling critical joints and consider corrosion-resistant grades or coatings in aggressive environments. Inspect mating threads for damage before installation and replace fasteners showing signs of galling or deformation.
