Würth #8 x 3" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Zinc, 3670000088961 2000 - 2000/Box

Wurth #8 x 3 Inch Flat Head Assembly Screw Use

Wurth #8 x 3 inch flat head assembly screw Phillips drive is a case hardened fastener designed for assembly work where a flat head needs to sit flush in the material. The #8 diameter and 3 inch length give solid bite and reach for thicker build-ups, so joints can be drawn tight in one pass. Its coarse thread design engages quickly in suitable substrates, helping pull components together with fewer turns. The Type 17 auger point starts into material with reduced walking, so holes can be started accurately at layout marks. The Phillips drive works with #2 Phillips drive bits, aligning with common shop drivers and reducing bit changes. A zinc finish provides a standard fastener surface that suits a wide range of indoor assembly tasks. This screw is sold by Wurth Baer Supply in full box quantities only, supporting consistent fastener choice across jobs.

Key Details That Support Assembly Results

• The #8 diameter combined with 3 inch length provides extended engagement in suitable materials, so installers can fasten through thicker components while still driving threads deeply into the base piece for a firm connection.
• The flat head design allows the screw head to sit flush with the surface when properly driven, which helps panels stack cleanly and creates a surface that is ready for additional components or finishing steps.
• The Type 17 auger point is shaped to start into the workpiece efficiently, so starting torque is reduced and the point can bite into the material with less wandering at the mark.
• The coarse thread geometry advances quickly through the material, so fewer turns are needed to pull parts together, which can shorten repeated assembly cycles on production or installation runs.
• The Phillips drive is specified to use #2 Phillips drive bits, so standard shop drivers and bit assortments can be used without searching for specialty drive patterns.
• The screw is case hardened according to the product description, giving a hardened outer layer that supports driving torque and helps the head and drive recess resist deformation during installation.
• The zinc finish provides a recognizable fastener surface that suits many interior assembly environments, helping keep fastener selection consistent across similar indoor projects.

Installation Behavior Of The Type 17 Coarse Thread Screw

This Wurth #8 x 3 inch flat head assembly screw uses a coarse thread that moves quickly through the substrate, so each trigger pull or hand drive translates into faster clamping of the joint. The Type 17 auger point begins cutting as it enters the material, which reduces the tendency to skate across the surface at startup. Because the head is flat, it can be driven until it seats level with the material, helping leave a surface that does not interfere with adjacent parts or applied finishes. The #2 Phillips drive in the head matches common bits, so the screw can be driven with typical drills or drivers that are already set up on site or in the shop. The case hardened structure supports this driving action by resisting cam-out damage at the recess during firm seating.

Where This Fastener Fits And Why Details Matter

Application Fit For #8 x 3 Inch Flat Head Screw

The Wurth #8 x 3 inch flat head assembly screw fits assembly situations that call for a relatively long fastener with a flush seating head. The combination of #8 diameter and 3 inch length means the screw can pass through one component and still have substantial thread length in the mating piece, so structural parts remain tightly drawn together. Its coarse thread form is suited to applications where rapid engagement in the material is desired, helping clamp components with fewer rotations and supporting faster rhythm on repetitive fastening. The Type 17 auger point at the leading end further supports placement by cutting into the material as it advances, so the point can follow the intended line into the workpiece and help installers keep alignment consistent across multiple fasteners.

Threading, Point, And Drive For Repeatable Results

The coarse thread on this assembly screw is described as running from the bottom of the screw toward the head, providing a strong pulling action once engaged, so joints can be tightened without excessive driver effort. The Type 17 auger point begins cutting immediately on contact, which reduces initial resistance and helps the screw enter the material smoothly, supporting repeatable starting behavior on both hand and powered drivers. Because the head is flat and uses a Phillips recess designed for #2 Phillips drive bits, the driver tip seats positively into the head, so torque can be transferred efficiently and the head can be driven cleanly to a flush position. The case hardened construction of the screw backs up this drive interface by giving the head and shank a hardened surface layer, supporting repeated firm driving without rapid wear at the recess or shaft. Together, these elements support consistent fastening performance across many identical assembly operations.
