Cone Point Set Screws

Cone Point Set Screws are precision-engineered fasteners designed to provide secure, positive locking in mechanical assemblies where alignment, adjustment, or resistance to movement is critical. These screws feature a sharply tapered cone-shaped point that penetrates the mating surface, creating a strong, localized grip that resists both rotation and axial motion. Commonly manufactured to ANSI B18.3, ISO 4027, or DIN 914 specifications, cone point set screws are used extensively in power transmission, machinery, tooling, and industrial equipment.

Constructed from durable materials such as alloy steel, stainless steel, or case-hardened carbon steel, these screws deliver excellent holding power and wear resistance. Alloy steel versions are often finished with thermal baked black oxide for corrosion protection and improved torque control, while stainless steel options offer superior performance in moisture-prone or corrosive environments.

The cone point design is particularly effective for applications where precise positioning is required—such as securing pulleys, gears, collars, and rotating shafts. The pointed tip creates a permanent indentation in the shaft surface, ensuring consistent locking under vibration, load, or torque fluctuations. This feature makes cone point set screws ideal for motor assemblies, couplings, instrumentation, and precision alignment tasks.

Available in both Fractional and metric sizes, with UNC, UNF, or metric coarse threads, cone point set screws are typically tightened using hex socket drives to allow easy installation and removal in tight spaces.

Engineered for maximum holding strength, repeatable performance, and versatility, the Cone Point Set Screw remains an essential fastener across countless mechanical and industrial applications—trusted by professionals who demand precision, reliability, and long-lasting engagement in every critical assembly.
