Value Collection 832033PR M4 X 0.70 X 25mm Flat Point Set Screw

Product Description

The VALUE COLLECTION 832033PR is an M4 x 0.70 x 25 mm flat point set screw manufactured from alloy steel to Grade 14.9 (45H), the highest strength class for metric set screws. A black oxide finish provides mild corrosion resistance and reduces light reflection in service environments. The hex drive socket accepts a 2 mm hex key for installation and removal. This fastener conforms to DIN 913 and ISO 4026 standards, making it suitable for precision mechanical assemblies where a flush or recessed clamping point is required. Machinists, tool-and-die makers, and maintenance technicians install this type of fastener to secure collars, pulleys, and shaft-mounted components without a protruding point.

Flat point set screws are used in applications where the mating shaft surface must remain undamaged or where a smooth, non-marring hold is preferred. Typical installations include light-duty shaft locking on CNC fixtures, rotary encoders, and mechanical drives operating in industrial or manufacturing environments. The M4 x 0.70 thread pitch is a standard metric coarse thread, common in precision machinery and instrumentation. This fastener is sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Grade 14.9 (45H) alloy steel construction for high clamping force in a compact M4 form factor
• Flat point geometry protects shaft surfaces from indentation and allows repositioning
• Black oxide finish for mild corrosion resistance and reduced surface glare
• 2 mm hex drive socket compatible with standard hex keys and L-wrenches
• Conforms to DIN 913 and ISO 4026 dimensional standards for international interchangeability
• Overall length of 25 mm measured as full fastener length

Compatibility

Designed as a standard DIN 913 and ISO 4026 metric flat point set screw in M4 x 0.70 thread size, compatible with any M4-tapped bore requiring a flat point grub screw of 25 mm overall length.

Installation Notes

Install using a calibrated 2 mm hex key or T-handle driver; do not use an undersized key, as this will round the socket. Verify that the receiving threaded bore is clean and free of debris before threading the fastener. Apply thread-locking compound if vibration is present in the application. Follow applicable machinery safety procedures and lock out or tag out equipment before performing fastener installation or removal on powered machinery.
