Product Description

The STARRETT SB248Z is a 4-piece pin punch set designed for driving pins, dowels, and roll pins in mechanical assembly, disassembly, and alignment work. Each punch features a round shank and an overall length of 8 inches, giving the user enough reach and control in tight workspaces. The set covers a size range from 0.0625 inches to 0.25 inches, with four individual sizes included: 1/4 inch, 3/16 inch, 5/16 inch, and 3/8 inch. The set ships in a protective pouch for organized storage and transport on the job site. It is well suited for mechanical tradespeople, HVAC technicians, and maintenance professionals who regularly work with pinned assemblies.

This pin punch set is intended for use in general mechanical and maintenance applications where precise pin removal or installation is required. Typical scenarios include removing hinge pins, aligning shaft components, and driving roll pins in HVAC equipment, plumbing fixture hardware, and general mechanical systems. The included size range makes it practical for a wide variety of fastener diameters encountered in residential and light commercial service work. The pouch storage keeps all four punches accessible and prevents loss between service calls.

Installation Notes

Pin punches are typically used by mechanical technicians and service tradespeople working on pinned assemblies. Always use a ball-peen or mechanics hammer appropriate to the task and ensure the workpiece is securely supported before driving. Wear appropriate eye protection when striking punches, as metal fragments can be ejected. Inspect each punch tip for mushrooming or deformation before use and replace any damaged punches to prevent slippage or injury.
