Value Collection -34859-5 Taper Pin Size 8 4 in Steel

Product Description

The VALUE COLLECTION -34859-5 is a Size 8 uncoated steel taper pin manufactured to ANSI/ASME B18.8.2 standards. It features a small end diameter of 0.4088 inches and a large end diameter of 0.492 inches, with an overall length of 4 inches. The pin is made from C-12L14 free-machining steel, which provides consistent dimensional accuracy and reliable shear performance in mechanical assemblies. Diameter tolerance runs from -0.0007 inches to +0.0013 inches, meeting standard precision requirements for taper pin applications. Machinists, maintenance technicians, and mechanical assemblers install this type of pin to secure hubs, collars, and levers to shafts in a wide range of industrial and commercial equipment.

This taper pin is suited for use in mechanical drive assemblies, machine tool components, and general industrial equipment where a reliable, removable shaft-to-hub connection is needed. The self-locking taper geometry holds the pin firmly under load without threads or adhesives, making it appropriate for both new assembly and repair work. It fits standard Size 8 taper pin holes reamed to ANSI/ASME B18.8.2 specifications.

Compatibility

Designed as an OEM-style replacement or new-installation taper pin for standard Size 8 taper pin bores reamed to ANSI/ASME B18.8.2 specifications in mechanical assemblies.

Installation Notes

Taper pins are installed by machinists or mechanical maintenance technicians using a standard taper pin reamer to prepare the bore before driving the pin. Always ensure the mating bore is properly reamed to the correct Size 8 taper before installation. De-energize and lockout/tagout all equipment before working on rotating or power-transmission components. Remove taper pins by driving from the small end using a suitable punch and hammer; do not use excessive force that may distort the bore.
