DeWALT Drive Pins with 0.300" Flat Head, Round Point, 0.145" x 3" Shank, and 1" Washer are heavy-duty powder actuated fasteners engineered for permanently attaching fixtures and structural components to concrete, concrete over steel deck, concrete masonry walls, and A36 or A572/A992 structural steel. The 1" washer increases the pin's bearing surface, distributing load more effectively and delivering a more secure, lasting hold in demanding construction applications. Sold in a convenient 100-pack, these drive pins are a reliable choice for framing crews, ironworkers, and contractors who need consistent fastening performance in tough base materials.

Key Features

• 0.300" flat head diameter - provides a broad, stable bearing surface that holds fixtures firmly against concrete and structural steel without pulling through
• 0.145" shank diameter x 3" shank length - sized for deep penetration into thick base materials, delivering strong pull-out resistance in permanent fastening applications
• Round point tip - engineered for clean, straight-line penetration into concrete and steel, reducing deflection during the driving operation
• 1" diameter washer included on each pin - increases the contact area at the face of the fixture, preventing pull-through and distributing the load across a wider surface
• Plastic flute mounted on the pin shank - retains the drive pin securely in the tool barrel and guides the fastener during driving for consistent, accurate placement
• Compatible with A36 and A572/A992 structural steel - meets the base material requirements of standard structural steel specifications used in commercial and industrial construction
• Knurled shank designs available - ideal for installations into thick steel base materials where added grip in the shank is needed to resist loosening
• 100-pack quantity - reduces job-site trips to the supply house and keeps crews working efficiently on high-volume fastening tasks

Why This Product

• Designed specifically for permanent fastening to concrete, concrete over steel deck, and structural steel - this pin addresses the most common base materials encountered in commercial framing and structural attachment work, making it a versatile single-product solution for multiple substrates.
• The 1" washer is built into each fastener, not a separate step - this saves installation time and ensures every pin delivers increased bearing surface without requiring the installer to handle loose washers in the field.
• The plastic flute retains the pin in the barrel of the powder actuated tool during loading and driving - this design detail reduces misfeeds, keeps the fastener aligned, and improves shot-to-shot consistency on demanding job sites.
• Packed in a 100-pin quantity - for contractors running powder actuated tools on large concrete or steel deck installations, this pack size supports sustained productivity without frequent restocking interruptions.

Frequently Asked Questions

What tool is used to drive these pins?

These are powder actuated fasteners designed for use with a compatible powder actuated tool. The plastic flute on the shank is specifically designed to retain the pin in the barrel of the tool and guide it accurately during the driving operation.

What is the purpose of the 1" washer on each pin?

The 1" washer increases the pin's bearing surface at the face of the fixture being fastened. This wider contact area helps distribute the load and prevents the fastener from pulling through the material, providing a more secure permanent connection.

Can these drive pins be used in treated lumber applications?

According to the product data, a mechanically galvanized (MG) coating version of these drive pins is available for use in treated lumber. The standard 50116-PWR pins are designed for concrete, concrete masonry, and structural steel base materials.

What is the difference between standard and knurled shank drive pins?

Standard shank drive pins are suitable for most concrete and steel fastening applications. Knurled shank designs feature a textured grip along the shank and are specifically intended for installations into thick steel base materials, where additional holding power in the base material is beneficial.
