Wurth #8 x 2-1/4 Inch Flat Head Assembly Screw

Wurth #8 x 2-1/4 inch flat head assembly screw defines this fastener as a #8 diameter, 2-1/4 inch long screw that handles typical woodworking and cabinet assembly joints where that reach is needed. The flat head detail means the screw seats flush in countersunk holes, so joined panels sit tight without raised heads disturbing alignment. The coarse thread description signals an aggressive bite in suitable materials, helping the screw pull parts together quickly in production-style work. The Phillips drive design works with #2 Phillips drive bits, which are standard in many shops, so installers can use familiar drivers without changing setups. The Type 17 auger point designation indicates a cutting-style tip that helps the screw start and advance with reduced resistance in appropriate applications, supporting smoother driving in repeated installations. The black finish gives the head a dark appearance, which matters where exposed fasteners need to visually blend with darker components.

Key Wurth Screw Details For Daily Work

• The #8 diameter and 2-1/4 inch length specification sets the screw up for fastening tasks that need moderate diameter with extended reach, helping installers tackle thicker build-ups and deeper joints using a known size standard.
• The flat head configuration lets the screw sit down into a countersink, creating a flush surface that supports tight-fitting faces or additional layers without interference from proud fastener heads during assembly.
• The coarse thread design engages material quickly along the threaded section, which pulls pieces together efficiently and supports repetitive driving in shop or site conditions where consistent draw is important.
• The Phillips drive detail is stated for #2 Phillips drive bits, so drivers and bits already common in woodworking and cabinet environments can be used, supporting straightforward driving across many fasteners on a job.
• The Type 17 auger point feature denotes a cutting-style tip that assists with starting and driving, so installers can move from one joint to the next with smoother screw entry and reduced resistance in suitable base materials.
• The black finish on the screw head provides a dark look at the surface, which supports applications where visible fasteners need to present a black appearance to coordinate with surrounding components.

Installation Details For Phillips Drive Assembly Use

The Phillips drive interface of this screw is specified for use with #2 Phillips drive bits, so power drivers and hand drivers set up with that bit size can engage the head properly during installation. The flat head geometry is suited for countersunk holes, allowing installers to drive the screw until the head seats at or below the material surface for a smooth finish in assembly work. The coarse thread description indicates an assertive thread form that advances through the material over the threaded portion, helping the screw draw components together as it is driven. The Type 17 auger point designation means the tip has a cutting characteristic that assists with entry into suitable substrates, supporting more controlled starts when placing multiple screws along a line of fastenings.

Using This Wurth Assembly Screw In Projects

Where This Coarse Thread Screw Fits Best

This product is identified as a Wurth #8 x 2-1/4 inch flat head assembly screw with coarse thread and a Type 17 auger point, so it is oriented toward tasks that combine panel joining with reliable thread engagement in appropriate materials. The 2-1/4 inch length gives reach for connections where installers must bridge thicker sections or multiple layers, allowing the threaded section to work over a useful depth of material. Since the flat head is designed to seat in a countersink, it fits applications where a flush or nearly flush surface is important, such as assembled components that will contact other parts or finished surfaces. The black finish allows this screw to serve fastening locations where a dark head is desirable at the surface, helping the visible fastener areas align visually with black or darker elements.

The coarse thread specification supports use in applications where an assertive pull is valued, as the threaded portion engages the substrate over fewer turns compared with finer threads. The Type 17 auger point further supports entry into suitable materials by using a cutting-style tip, which helps the screw advance with reduced initial resistance as it bites. Together, the thread style and auger point help installers maintain a steady driving rhythm when placing many fasteners in sequence, especially in repetitive assembly tasks. The #8 diameter provides a familiar balance between strength and hole size in assembly work, keeping the fastener footprint consistent with other #8 screws already used in many woodworking and cabinet projects.

Why These Wurth Details Support Consistent Results

The specified #2 Phillips drive pairing with this Phillips drive head allows drivers already set up with that bit size to maintain positive engagement, which helps reduce cam-out during driving and supports cleaner head recesses. This matters when many screws are driven in a pattern, because consistent bit fit can contribute to even seating depth and appearance across a run of fasteners. The flat head shape, when matched with correctly sized countersinks, allows the head to bear evenly against the material surface, which supports uniform clamping force around the joint area.

The case hardened description indicates that the screw has undergone a hardening process, which is significant for maintaining thread form and head integrity under driving torque in typical use. This helps the threads stay defined as they cut into the material during installation, supporting repeatability across multiple fastening points on a job. The note that 3/4 inch and 1 inch lengths are threaded fully while all other sizes are threaded two-thirds from the bottom of the screw shows that the 2-1/4 inch length sits in the group threaded two-thirds from the bottom, so the upper shank remains unthreaded. That thread layout lets the lower portion of the screw pull the joint tight while the unthreaded shank section passes through the first component, which can aid in drawing the pieces together. These details combine to provide a screw configuration that supports consistent seating, thread engagement, and joint draw in assembly applications using this specific length.

Common Questions About This Wurth Assembly Screw

Selecting This Screw For Assembly Projects

The Wurth #8 x 2-1/4 inch flat head assembly screw pairs a coarse thread, Type 17 auger point, and case hardened construction with a black finish, making it suitable where this specific size and appearance are needed. Using a Phillips drive designed for #2 bits, it fits directly into common shop driver setups and supports consistent fastening. For projects that call for this length, thread layout, and head style, choosing this screw lets installers match their assembly approach to a clearly defined fastener specification.
