Proto J48516LS2 Long Pin Punch 5/16 in S2 Steel

Product Description

The PROTO J48516LS2 is a long pin punch manufactured from S2 steel, designed for driving pins, bolts, and dowels in mechanical and maintenance applications. With a 5/16-inch punch diameter and an 8-inch overall length, this tool reaches into confined areas where standard-length punches fall short. S2 steel construction provides the toughness and shock resistance required for repeated hammer strikes without chipping or deforming the tip. It is used by maintenance technicians, machinists, ironworkers, and trade professionals working on equipment disassembly and assembly tasks.

This long pin punch is suited for industrial maintenance, mechanical repair, and trade work where pins, roll pins, or dowels must be driven through assemblies. The extended 8-inch length allows technicians to reach deeply recessed pins in machinery, frames, and structural components. It is commonly used in HVAC equipment servicing, plumbing fixture disassembly, electrical panel work, and general mechanical trades where precision pin removal or setting is required.

Key Features

• 5/16-inch punch diameter for precise pin driving and removal
• 8-inch overall length provides extended reach into deep or confined assemblies
• S2 steel construction delivers high impact toughness and resistance to chipping
• Compact cross-section of 0.4 inches height and 0.4 inches width for tight-clearance work
• Lightweight at 0.32 pounds for reduced hand fatigue during extended use

Compatibility

Designed as a general-purpose long pin punch for use with standard ball-peen or mechanics hammers in mechanical disassembly and assembly tasks across trade and industrial settings.

Installation Notes

Pin punches are installed by hand tool use only — always use an appropriate hammer matched to the punch size and application load. Secure the workpiece firmly before driving to prevent movement or damage. Wear appropriate eye protection when striking, as metal fragments can dislodge. Do not use a punch with a mushroomed or deformed head; inspect the tool before each use.
