Value Collection MSC67702043X Taper Pin Size 5 Stainless

Product Description

The VALUE COLLECTION MSC67702043X is a Size 5 taper pin machined from 303 grade 18-8 stainless steel with a passivated finish. It features a small end diameter of 0.2578 inches and a large end diameter of 0.289 inches, with an overall length of 1.5 inches. The tapered profile provides a secure, self-locking fit when driven into a matching reamed hole, resisting loosening under vibration or cyclic loading. Licensed machinists, millwrights, and maintenance technicians use taper pins to align and secure hubs, collars, and levers to shafts in mechanical assemblies across industrial and commercial equipment.

This taper pin is suited for use in mechanical assemblies where a removable, precision locating or locking fastener is required. Common applications include shaft-to-collar connections, gear hubs, pump components, and general machine assembly work where corrosion resistance is a priority. The 303 stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or food-adjacent processing equipment. It conforms to ANSI/ASME B18.8.2 standards, making it a direct fit wherever that specification is called out on engineering drawings.

Compatibility

Designed as an ANSI/ASME B18.8.2 compliant Size 5 taper pin for use in any mechanical assembly specifying a standard Size 5 taper pin in 303 or 18-8 stainless steel.

Installation Notes

Taper pins are installed by machinists or maintenance technicians using a taper pin reamer to prepare the mating hole to the correct taper before driving the pin. Always de-energize and lock out equipment before performing fastener work on rotating or reciprocating assemblies. Drive the pin with a pin punch and hammer until seated; never force an oversized pin into an unprepared hole. Removal is accomplished by driving from the small end with a punch of appropriate diameter.
