Value Collection 34857 Taper Pin Size 7 2in Steel C-12L14

Product Description

The VALUE COLLECTION 34857 is a Size 7 taper pin machined from C-12L14 steel and supplied in an uncoated finish. Taper pins are precision-ground fasteners used to locate, align, or lock components on shafts and in assemblies. This pin measures 2 inches overall length, with a small end diameter of 0.3674 inches and a large end diameter of 0.409 inches. The lead-bearing C-12L14 steel grade provides good machinability and consistent dimensional accuracy, making it a practical choice for general mechanical assembly work in maintenance, manufacturing, and industrial service environments. Machinists, millwrights, and maintenance technicians are the typical installers.

Size 7 taper pins conforming to ANSI/ASME B18.8.2 are used across a wide range of mechanical assemblies where a removable, self-locking alignment or retention method is needed. Common applications include shaft-to-hub connections, gear and pulley retention, jig and fixture alignment, and light structural alignment in machinery. These pins are driven into tapered reamed holes and rely on their taper geometry for a secure friction fit without threads or adhesives. The 10-piece package quantity suits bench stock, maintenance kits, and small-run production needs.

Key Features

• ANSI/ASME B18.8.2 standard compliance ensures dimensional interchangeability with other conforming Size 7 taper pins
• C-12L14 free-machining steel grade supports consistent surface finish and tight tolerance control
• Small end diameter of 0.3674 inches with minimum diameter tolerance of 0.0007 inches and maximum diameter tolerance of 0.0013 inches
• 2 inches overall length suits a broad range of hub depths and assembly thicknesses
• Uncoated finish allows inspection of surface condition and is suitable for use with added corrosion protection where required
• Sold in a 10-piece package quantity for bench stock and small-run use

Compatibility

Designed as a standard ANSI/ASME B18.8.2 Size 7 taper pin replacement or new-installation fastener for any mechanical assembly requiring a tapered reamed hole sized to accept a Size 7 pin.

Installation Notes

Taper pins are installed by machinists, millwrights, or maintenance technicians using a properly sized tapered reamer to prepare the hole before driving the pin. Always de-energize and lock out the equipment before disassembling shaft or hub components. Drive pins with a hammer and pin punch sized to the small end diameter; do not strike the large end directly. Removal is performed from the small end using a punch to avoid deforming the seating surface.
