Würth #8 x 1-1/4" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Black, 3670000072961 5000 - 5000/Box

Wurth #8 Flat Head Assembly Screw Purpose

Wurth #8 x 1-1/4 flat head assembly screw is a coarse thread, black screw with a Type 17 auger point and #2 Phillips drive, so it handles standard assembly work where a flush flat head and quick start are useful. The coarse thread works with the Type 17 auger-style point to bite efficiently from the bottom of the screw, which matters when pulling materials together without long spin time. This screw is case hardened, so the core is engineered for strength with a hardened shell that supports driving into demanding assemblies. The flat head design sits down into a countersunk recess, which helps create a clean surface in finished work. The black finish presents a dark, uniform appearance on exposed fastener heads, which matters wherever visible hardware needs a consistent look across a project.

Key Details That Support Assembly Work

• The #8 diameter combined with 1-1/4 inch length provides a common assembly size, so it fits many everyday fastening tasks where moderate penetration and holding power are required.
• The flat head profile is designed to sit flush in a countersunk hole, which helps reduce snag points and keeps surfaces cleaner on assembled components.
• The Type 17 auger point is built for aggressive starting at the bottom of the screw, which helps the screw cut in quickly and reduce wandering as threads engage.
• The coarse thread configuration is tailored to bite firmly through material with fewer turns, which speeds installation when driving many screws in succession.
• The #2 Phillips drive matches standard #2 Phillips bits, so installers can use common drivers and keep bit changes to a minimum during repetitive work.
• The case hardened construction gives the screw a hardened exterior over a strong core, which supports driving torque demands in typical assembly situations.
• The black finish provides a dark head color, which matters when fasteners remain visible and a consistent black appearance is preferred across the job.

Assembly Screw Fit, Drive, And Thread Behavior

This #8 x 1-1/4 inch coarse thread assembly screw is sized to pull components together without excessive over-penetration, which supports controlled fastening in common build-ups. The flat head form is intended to nest into a compatible countersink, creating a smoother running surface across the joined parts. Its Type 17 auger point is shaped to start cutting at the bottom section of the screw, which helps the point feed into material and bring the coarse threads into play quickly. Using a #2 Phillips drive means the screw is driven by widely available bits, so drivers and impact tools already set up with #2 Phillips can handle the work. The case hardened construction supports torque during drive-in, which matters when running multiple screws in sequence on a project.

Using This Wurth Screw In Real Projects

Where This #8 Assembly Screw Is Applied

This Wurth #8 x 1-1/4 flat head assembly screw is part of the screws product class in the fasteners category, so it is intended for general assembly fastening tasks where a countersunk flat head is preferred. The coarse thread, working from the lower two-thirds of the screw, is well suited to pulling materials tightly together once the Type 17 auger point has established the path. The 1-1/4 inch length makes it appropriate wherever material thickness and design call for a moderate-length fastener rather than a short or extra-long option. The black finish allows this screw to be used in assemblies where the fastener head remains visible and a darker tone is desired across the installation. As a Wurth-branded fastener with part number 3670000072961 5000, it aligns with the wider range of screws used throughout woodworking and related assembly work.

Details That Support Repeatable Fastening Results

The case hardened design of this screw provides a structure where the outer surface is hardened while the core is built to carry load, which supports repeated driving forces and typical assembly stresses. The Type 17 auger point is intended to start cutting as soon as the screw engages, so the installer benefits from quicker thread engagement and more predictable entry as the coarse threads advance. With a flat head that seats into a countersunk hole, each installed screw can present a similar flush finish, which helps maintain consistent clearances on doors, panels, or other moving parts that pass over the fastened area. The #2 Phillips drive standardization aligns with common bits found in shops and on sites, so each screw can be driven with familiar tools and techniques. The coarse thread pattern concentrates holding power over the threaded portion of the shank, which supports tight draws between joined components within the available length.

Common Questions About This Wurth Assembly Screw

Selecting This Screw For Assembly Tasks

The Wurth #8 x 1-1/4 flat head assembly screw with #2 Phillips drive, coarse threads, and Type 17 auger point gives a balanced mix of length, bite, and drive style for general fastening work. Its case hardened construction supports typical driving torque demands, while the flat head design allows a flush, countersunk finish where surfaces need to stay clean. The black finish provides a consistent dark appearance on visible heads. When an assembly calls for a #8 diameter, 1-1/4 inch flat head screw with a Type 17 point and coarse threads, this Wurth part number 3670000072961 5000 offers those specific characteristics in a single fastener choice.
