23 Gauge Headless Pinner

SKU: P650 Categories: ,


Setting a precedence, GREX continues to push the limit with its popular line of 23-gauge headless pinners. First of its kind, the GREX P650 sports a 2″ fastener capability. Now you have the ability to drive even longer fasteners into soft or hardwood with the same great quality and features expected from GREX.

High Tolerance – Posit-Lock™ Nose Cover: The high tolerance precision machined hardened steel driver, nose cover and nose guide assembly aligns and seats the headless pin for optimal drive performance. What is Posit-Lock™ – it’s tight tolerance, durability and functionality that reduces jams to a minimum.

Performance Enhanced Innovative Patented Magazine: The GREX P650 sports a lightweight aluminum (not plastic) extruded magazine; stair-stepped magazine, increasing access to tighter areas and more angles; automatically adjusts to pin size, accepts headless pins from 3/8″ to 2″; a rear magazine cap allows for both hex wrench and spare no-mar tip storage; has a durable yet operator friendly magazine latch; and last but not least a fastener supply window showing pin supply.

What’s more: A swivel disconnect, prevents air-hose tangles; detachable no-mar tip, prevents project damage; the no-mar tip has four sight guidelines, increasing pinning accuracy; side bumpers, prevent tool and project damage; convenient belt hook; and rear exhaust using a silencer.
