The VALUE COLLECTION A410173 is a metric hex socket cap screw designed for precision fastening in mechanical assemblies, fabrication work, and equipment repair. This screw features an M4 x 0.70 thread and a 25 mm length under head with partial threading along the shank. The drive type is hex socket, requiring an Allen key or hex bit for installation. Manufactured from 316 stainless steel with an austenitic Grade A4 rating, it delivers strong corrosion resistance in wet, marine, and chemically exposed environments. The uncoated bright finish meets DIN 912 dimensional standards. Each package contains 25 screws.
These cap screws are suited for light mechanical assemblies, instrumentation mounting, plumbing fixture hardware, and any application where corrosion resistance and dimensional accuracy are required. The M4 thread size is common in HVAC control panel assemblies, electrical enclosures, pump housings, and pool equipment brackets. Grade A4 316 stainless construction makes these appropriate for outdoor, coastal, or chemical-wash environments where carbon steel fasteners would corrode. Installers working across plumbing, mechanical, or electrical trades will find these a reliable match for metric-spec equipment.
Designed as a standard DIN 912 metric hex socket cap screw suitable for M4 x 0.70 threaded applications in mechanical, plumbing, electrical, and HVAC assemblies requiring stainless steel fasteners.
Install using a correctly sized hex key or hex driver bit to avoid rounding the socket recess. When fastening into tapped holes, verify the thread pitch matches the receiving material before applying torque. Grade A4 stainless fasteners are generally not compatible with carbon steel tap sets due to work-hardening characteristics. Follow applicable mechanical or equipment manufacturer torque guidance for M4 fasteners in the specific assembly.
