Senco 21 gauge medium head pin brings straight strip pin head nails to trim and finish jobs where a thin 21 gauge fastener is preferred. The 1-3/8 inch length allows these pins to reach through standard trim and light wood assemblies, giving holding power without a bulky shank. The medium head design creates a small yet positive bearing surface against the material, helping the pin seat cleanly. These pin head nails are part of Senco Products, Inc. pin head nail class, so they match tools designed around that fastener style. A glued strip collation holds the pins in a straight strip, feeding smoothly through compatible tools. The chisel point tip is shaped to enter wood efficiently, which supports controlled driving in typical woodworking conditions.
These Senco ZX16EAA 21 gauge x 1-3/8 inch medium head pins are for use with the Senco Finish Pro 21LXP, so they match that tool's magazine and driver setup. Because the pins are straight strip, they align with the straight-path feed of the Finish Pro 21LXP, supporting predictable cycling while fastening. The glued strip collation works with that magazine style by holding the fasteners in a solid strip until driven, which supports steady advancement under normal air tool operation. With a chisel point, the pins are shaped to enter wood as the Finish Pro 21LXP drives them, helping the tool deliver clean penetration into trim and light assemblies. Matching the 21 gauge designation, the pins are sized to suit the driver dimensions in that model for efficient seating and repeatable results.
These Senco 21 gauge straight strip pins sit in the pin head nails category, placing them in applications where a small head fastener is required instead of a larger brad. The medium head provides a modest bearing surface, which suits trim or light assembly tasks where some hold is needed but a large nail mark is not desired. At 1-3/8 inch long, each pin can pass through typical thin trim stock and into a backing component, helping tie parts together while keeping the fastener profile fine. The 21 gauge rating puts these pins between heavier brads and finer micro pins, matching jobs that need a balance between minimal surface impact and basic retention in wood. Because they are for use with the Senco Finish Pro 21LXP, they serve well wherever that tool is already in the workflow.
The straight strip pins are arranged to feed linearly through a magazine, which supports consistent driving patterns and reduces interruptions compared to loose fasteners. Glued strip collation bonds each pin to its neighbors in the strip, keeping the row intact as it advances, which helps the driver blade meet each pin squarely. The chisel point at the tip is shaped to contact the wood with a focused edge, helping the pin start into the surface rather than skidding, which is useful on typical trim profiles. Being classed as pin head nails from Senco Products, Inc., these pins are designed around pin nailer mechanics, supporting tool alignment, driver fit, and nosepiece design in that family. The combination of 21 gauge size, medium head, and 1-3/8 inch length creates a consistent fastener profile, which supports repeatable depth settings and aesthetic results across a run of work.
The Senco ZX16EAA medium head pins are 21 gauge and 1-3/8 inch long, giving a slim shank that can pass through trim and into backing material for light fastening tasks.
These 21 gauge medium head pins are for use with the Senco Finish Pro 21LXP, so they fit that tool's magazine and driver system for straightforward pinning work.
