Value Collection BHS7X04025-050BX M4x0.7 Button Cap Screw 50pc

Product Description

The VALUE COLLECTION BHS7X04025-050BX is a partially threaded button socket cap screw manufactured from A2 (18-8) stainless steel with a bright, uncoated finish. The fastener features an M4x0.7 metric thread and a 25 mm length under head, driven by a 2.50 mm hex socket. The button head profile provides a low-profile clamping surface suitable for applications where clearance is limited. Conforming to ANSI/ASME B18.3.4M and ISO 7380 standards, this screw is appropriate for assemblies requiring corrosion resistance and dimensional consistency. Sold in a minimum order quantity of 50 pieces per box.

This fastener is suited for light to medium-duty mechanical assemblies across manufacturing, maintenance, and equipment fabrication environments. The M4 metric thread and right-hand thread direction make it compatible with standard M4 threaded holes and inserts. The A2 stainless steel construction resists rust and mild chemical exposure, making it a practical choice for indoor and moderate outdoor applications. Machinists, maintenance technicians, and fabricators commonly use this screw when a low-profile head and metric sizing are required.

Key Features

• Button head, low-profile design for clearance-restricted installations
• M4x0.7 metric thread with right-hand direction and 6G thread fit class
• 25 mm length under head, partially threaded
• 2.50 mm hex socket drive for standard Allen key or hex bit installation
• A2 (18-8) stainless steel for corrosion resistance
• Meets ANSI/ASME B18.3.4M and ISO 7380 fastener standards

Compatibility

Designed as a standard ISO 7380 button socket cap screw for use in any M4x0.7 threaded assembly requiring a low-profile head and metric fastener specification.

Installation Notes

Installation is performed using a 2.50 mm hex key or matching hex socket bit. Verify that the mating thread is clean and free of debris before driving the fastener. Apply appropriate thread-locking compound or torque per the assembly engineering specification when vibration or load cycling is expected. Avoid over-tightening, as the button head has a lower torque threshold than a standard socket cap head of the same diameter.
