Value Collection 832800PS M20 Set Screw Flat Point Alloy Steel

Product Description

The VALUE COLLECTION 832800PS is an M20 x 2.50 x 25 mm flat point set screw manufactured from alloy steel at material grade 14.9 (45H). It features a hex drive socket and a black oxide finish, conforming to DIN 913 and ISO 4026 standards. This headless fastener is designed to secure a component — such as a collar, gear, or pulley — against a shaft by applying direct axial pressure through the flat tip. Machinists, millwrights, and maintenance technicians install this type of set screw in mechanical assemblies where the fastener must sit flush with or below the surface of the host component.

This set screw is suited for industrial and mechanical applications requiring a metric M20 thread form. The flat point tip distributes clamping force over a broader contact area compared to cup or cone points, making it appropriate for use on hardened shafts or surfaces where minimal surface marking is required. The black oxide finish provides a base level of corrosion resistance and reduces light reflection in precision assemblies.

Key Features

• M20 x 2.50 thread size, 25 mm overall length — fully metric dimensioning per ISO 4026 and DIN 913
• Flat point geometry distributes load across shaft surface, reducing shaft damage
• Grade 14.9 (45H) alloy steel construction for high tensile and torsional strength
• Hex drive socket accepts a 10 mm hex key for installation and removal
• Black oxide finish for mild corrosion resistance and low-glare appearance

Compatibility

Designed as a standard metric set screw conforming to DIN 913 and ISO 4026, compatible with M20 x 2.50 threaded bores in mechanical assemblies requiring a flat point headless fastener.

Installation Notes

Installation requires a 10 mm hex key (Allen wrench). Ensure the receiving bore is clean and threads are free of debris before driving the screw. De-energize and lockout any machinery before servicing components that contain set screws. Do not exceed the torque capacity of the alloy steel grade by using extensions that could strip the hex socket.
