RS PRO Plain Steel Hex Socket Countersunk Screw M4 x 10 mm DIN 7991 Grade 10.9 281-423

RS PRO 281-423 Plain Steel Hex Socket Countersunk Screw M4 x 10 mm is a high-quality metric fastener engineered for flush mounting and reliable securing of components in industrial environments. The hexagon socket countersunk head design enables the screw to sit flush or below the surface, making it ideal for applications where space and safety are critical.

Constructed from robust grade 10.9 steel, this screw offers superior strength and resilience compared to standard grade fasteners. Its black oxide plain finish not only enhances corrosion resistance but also provides an attractive aesthetic in exposed locations. With an M4 thread diameter and 10 mm length, it fits a wide range of machinery, equipment, joinery, and panel assembly tasks.

The countersunk profile ensures the head does not protrude, minimizing interference with moving parts or neighboring components. Installation and removal are straightforward using a hex (Allen) key, which also prevents slippage and damage during tightening.

Performance parameters such as nominal strength of 1040 N/mm² and yield strength of 940 N/mm² attest to its suitability for high-stress applications. DIN 7991 conformity guarantees precision manufacture and compatibility across international projects.

Typical applications include woodworking, industrial machines, electronic panel building, automotive assemblies, medical device construction, security guarding, and maintenance operations. Its engineering provides reliable, vibration-resistant clamping and is frequently used where repeated fastening and unfastening are required.
