The VALUE COLLECTION 531040PR is a metric low socket cap screw designed for applications where a reduced head height is required to clear adjacent components or fit within shallow counterbores. Manufactured from grade 10.9 alloy steel with a black oxide finish, this fastener delivers high tensile strength and moderate corrosion resistance in a compact head profile. The fully threaded M4x0.7 shank runs the full 10mm length under the head, and the 2.5mm hex socket drive accepts a standard hex key for secure installation in tight spaces.
This screw is suited for mechanical assemblies, machine building, tooling fixtures, and precision equipment where standard socket head cap screw height clearance is not available. The metric M4x0.7 thread pitch and grade 10.9 strength class make it a common choice in industrial manufacturing, automation, and light structural applications. It conforms to fastener standard SIP 147 and carries UNSPSC code 31161501. Installation is typically performed by millwrights, machine builders, or mechanical technicians using a 2.5mm hex key or hex bit driver.
Designed as a metric replacement or stock fastener for assemblies requiring a fully threaded M4x0.7 low socket cap screw with a 10mm length under head per SIP 147.
Installation is performed using a 2.5mm hex key or hex bit driver. Ensure mating threads are clean and free of debris before installation. Do not over-torque grade 10.9 fasteners into softer base materials such as aluminum or plastic. Minimum order quantity is 100 pieces per order.
