Würth #8 x 2-1/4" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Zinc, 3670000086961 2500 - 2500/Box

Wurth #8 x 2-1/4 Screw For Assembly Work

Wurth #8 x 2-1/4" flat head assembly screw gives you a case hardened fastener designed for structural joining, so joints resist wear in service. The flat head design seats flush in a countersunk hole, which keeps surfaces smooth for cabinet and woodworking applications.

The Type 17 auger point at the tip starts aggressively into the material, which helps the screw bite quickly when driving into wood-based substrates. The coarse thread pattern on this screw moves material efficiently as it drives, which supports strong holding in softer woods and composite materials where deep thread engagement is important.

This screw uses a #2 Phillips drive, so installers can use widely available #2 Phillips drive bits during assembly. The zinc finish on the screw provides a plated surface, which matters where a standard zinc-colored appearance is desired on exposed or semi-exposed fastener heads.

Key Wurth Assembly Screw Details For Pros

• The #8 screw size establishes a familiar diameter for cabinet and woodworking assembly, which aligns with common pilot drilling and driver setups on site.
• The 2-1/4" length provides reach for joining thicker stock combinations, which helps fasten through face material into framing or internal components.
• The flat head pattern allows the screw to sink into a countersunk recess, which keeps hardware and panels sitting flush over the fastened area.
• The Type 17 auger point design supports fast starting in wood substrates, which reduces wandering at the start of the drive and aids repeatable placement.
• The coarse thread configuration delivers deep bite in softer materials, which supports strong pull-down force on workpieces during assembly.
• The #2 Phillips drive interface matches standard Phillips bits, which keeps tool changes simple across large runs of similar fasteners.

Assembly Screw Drive And Thread Behavior In Use

This Wurth assembly screw combines a #2 Phillips drive with a Type 17 auger point so torque transfers smoothly from bit to screw while the point cuts into the substrate, which helps maintain control through the drive. The coarse thread form advances the screw efficiently, so the shank moves into the work with fewer revolutions and strong pull-down on the joint.

Case hardened construction stabilizes the screw body as torque loads increase, which supports consistent driving without deforming the head in normal assembly operations. The zinc finish gives the screw a bright plated look, which coordinates visually with other zinc-finished fasteners on the same project.

Using This Wurth Screw In Woodworking Assembly

Where The Wurth Assembly Screw Works Best

This Wurth #8 x 2-1/4" flat head assembly screw fits jobs that call for a case hardened fastener with a countersunk head, so the head can sit level with the surface in cabinet or woodworking components. The coarse thread geometry is suited to wood-based sheet goods and solid lumber where threads need to grip deeply through the engaged length.

The screw length helps span face material and into framing or blocking, which is useful where components of different thicknesses must be drawn tightly together. The zinc finish provides a neutral metallic appearance on the visible head, which integrates cleanly with other zinc screws used throughout an installation.

How Drive, Point, And Threads Aid Workflow

The #2 Phillips drive on this screw aligns with standard bits already common in drills and drivers, which allows crews to move across different tasks without changing driver style. The Type 17 auger point starts into wood substrates with a cutting action, which helps the point clear a path for the coarse threads as they follow.

Because this screw is case hardened, the structure of the fastener resists deformation as torque builds during driving, which supports repeated fastenings in production environments. The coarse thread pattern advances rapidly through the workpiece, which can shorten drive time per screw while still generating strong clamping between assembled parts.

Common Questions About This Wurth Assembly Screw

Selecting This Screw For Assembly Tasks

The Wurth #8 x 2-1/4" flat head assembly screw Phillips drive - Type 17 auger point coarse thread zinc combines case hardened construction, countersunk head geometry, and a #2 Phillips drive, which supports controlled driving and strong engagement in wood-based assembly work.

The zinc finish, coarse thread pattern, and Type 17 auger point all work together to deliver fast starts, solid bite, and a clean plated look, which suits cabinet, woodworking, and general assembly projects built around zinc-colored fasteners.
