The VALUE COLLECTION 531092PR is a low socket cap screw designed for metric fastening applications where a reduced-profile head is required. Manufactured from alloy steel at material grade 10.9, this screw delivers high tensile strength in a compact form factor. The black oxide finish provides light corrosion resistance and a uniform matte appearance. The M6x1 thread pitch and 8mm length under head make it a practical choice for close-tolerance assemblies. Drive is a 4mm hex socket, compatible with standard hex key and socket drive tools. It is fully threaded along its usable shank length and conforms to SIP 147 fastener standard.
This screw is suited for mechanical assemblies, machine fixtures, and industrial equipment where a low-profile head is necessary to clear adjacent components or fit within recessed counterbores. The metric M6x1 thread size is common across a wide range of manufactured equipment, making this screw applicable to general mechanical, maintenance, and fabrication work. It is typically installed by machinists, millwrights, maintenance technicians, and production assembly personnel. Minimum order quantity is 100 pieces; each package contains 1 piece.
Designed as a metric replacement or maintenance fastener for assemblies requiring an M6x1 low socket cap screw with a 4mm hex drive, conforming to SIP 147 standard. Verify thread engagement depth and head clearance before installation.
Installation should be performed by qualified mechanical or maintenance personnel using a calibrated 4mm hex key or socket driver. Confirm mating thread condition and clean threads before assembly to achieve proper clamp load at grade 10.9 specification. Do not exceed the torque capacity appropriate for the mating material and thread engagement length. Black oxide finish does not substitute for heavy corrosion protection coatings in wet or chemical environments.
