Value Collection 832120PS M8x1.25x40mm Flat Point Set Screw

Product Description

The VALUE COLLECTION 832120PS is an M8 x 1.25 x 40 mm flat point set screw manufactured from alloy steel to Grade 14.9 (45H). It features a 4 mm hex (Allen) drive socket and a black oxide finish that provides a baseline level of corrosion resistance. This screw is manufactured to DIN 913 and ISO 4026 dimensional standards, making it a metric fastener suitable for precision mechanical assemblies where a flush or recessed locking point is required. Machinists, millwrights, and maintenance technicians typically install this type of fastener to secure collars, pulleys, gears, and similar components to shafts without protruding hardware.

This flat point set screw is suited for general industrial and mechanical applications where the fastener must bear against a shaft or mating surface without creating a raised drive point. The flat point distributes clamping load across the shaft surface and is commonly selected when the shaft must remain undamaged or when rotational indexing and repositioning are anticipated. It is appropriate for use in light-duty to moderate mechanical assemblies in manufacturing, maintenance, and repair environments.

Key Features

• M8 x 1.25 thread size with 40 mm overall length for solid engagement depth
• Flat point geometry distributes load and reduces shaft marring compared to cup or cone points
• Grade 14.9 (45H) alloy steel construction provides high tensile and torsional strength
• 4 mm hex key drive for precise torque application with standard Allen wrenches
• Black oxide finish for a uniform appearance and mild corrosion resistance
• Manufactured to DIN 913 and ISO 4026 standards for dimensional consistency

Compatibility

Designed for use in metric fastener applications conforming to DIN 913 and ISO 4026 standards. Suitable for M8 x 1.25 threaded bores in collars, hubs, gears, and mechanical assemblies requiring a flat point set screw.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using a properly sized 4 mm hex key to avoid drive socket rounding. Ensure the threaded bore is clean and free of debris before installation. Do not exceed the torque capacity of the fastener, and verify that mating thread condition and class are compatible with the M8 x 1.25 thread specification. Power down and de-energize any rotating equipment fully before servicing components secured by set screws.
