    Würth #8 x 1-1/2" Flat Head Assembly Screw Square Drive - Type 17 Auger Point Coarse Thread Black, 3670000353961 5000 - 5000/Box

    Description

    #8 Assembly Screw For Strong Flat Head Joints

    #8 x 1-1/2 flat head assembly screw gives you a coarse-thread fastener sized for common woodworking and assembly jobs, so installers can tie components together with predictable bite and consistent clamping along the joint. The flat head design seats flush into countersunk holes, which keeps surfaces even where hinges, slides, or panels meet. This screw uses a square drive recess, so #2 square drive bits engage securely and transfer torque with less cam-out during production or installation work. The screw length and coarse thread pattern support pull-together force in thicker material stacks, which helps close gaps when drawing parts tight. The black finish offers a dark fastener appearance, which can visually blend with dark components where exposed heads matter. For repeat work, the consistent #8 diameter and 1-1/2 inch length simplify setup when matching pre-drilled patterns.

    Key Screw Details That Support Daily Work

    • The coarse thread on this #8 x 1-1/2 screw is designed for strong bite in suitable materials, which helps pull joints together firmly on assembly runs.
    • The flat head profile lets the screw seat into countersinks, creating a flush surface that supports smooth hardware mounting and clean panel alignment.
    • The #2 square drive requirement matches standard square drive bits, so drivers engage positively and maintain control across repetitive fastening tasks.
    • The Type 17 auger point is engineered to start aggressively into the material, which reduces wandering at the start of the drive and supports more accurate placement.
    • The case hardened construction gives the screw a hardened shell, supporting torque transfer at the head and shank during power driving in shop or jobsite conditions.
    • The black finish provides a dark head color, which is useful where the head remains visible on dark components or trim pieces.

    Installation Behavior Of This Square Drive Screw

    The square drive recess on this screw is sized for #2 square drive bits, so drivers seat firmly in the head and let installers transmit torque without frequent bit slippage. The Type 17 auger point is designed to cut its way into the material, which helps the point start in the mark and draw the screw in with less initial resistance. Coarse threads on the #8 body advance quickly through appropriate substrates, which helps tighten components together with fewer turns and supports efficient cycle times. The flat head form allows the screw to sink into a countersunk hole until it sits level with the surface, which keeps mating parts from rocking on raised heads. Case hardened construction keeps the exterior of the screw harder under driving loads, which supports head integrity under the square drive and helps the shank tolerate powered installation.

    How This Wurth Assembly Screw Fits Your Workflow

    Using The #8 x 1-1/2 Screw In Assemblies

    The #8 x 1-1/2 flat head assembly screw gives fabricators a standard-length fastener that suits many multi-layer build-ups, so one size can serve a range of cabinet and component joints. With coarse threads extending through the working section, the screw creates a strong pull between pieces as it advances, which is useful when pulling slightly bowed parts into alignment. The flat head geometry lets the fastener sit down into a countersunk or drilled recess, helping overlay pieces meet cleanly without interference. Its black finish allows the head to visually recess against darker substrates, which can be useful in exposed interior locations where head color matters. Because the screw is case hardened, installers can run it with drivers at production speeds while the hardened exterior supports the torque needed to seat the head firmly.

    Details That Help Repeatable Driving And Alignment

    The #2 square drive interface works with common square drive bits, so crews can standardize on one bit style and achieve consistent engagement from screw to screw. That positive engagement helps keep the bit centered in the recess, supporting straighter driving and reducing wobble as the screw starts. The Type 17 auger point is designed to cut into the material at the tip, which reduces the effort required to break the surface and helps the screw follow its starting line. As the coarse threads advance, they move the screw forward rapidly, which supports quick clamping of parts and reduces driver run time per fastener. The flat head profile allows the head to compress fibers around the countersink as it seats, aiding tight contact between pieces. With a case hardened body, the screw maintains a hard surface at the head and threads during installation, which supports reliable driving from the first screw through large batch runs.

    Common Questions About This Wurth Assembly Screw

    What size is this Wurth assembly screw?

    This Wurth screw is a #8 x 1-1/2 inch flat head assembly screw, which defines the screw diameter and length and helps match it to pre-drilled patterns and material thicknesses.

    What drive style does this assembly screw use?

    This assembly screw uses a square drive designed for #2 square drive bits, which allows the bit to seat securely in the head for controlled torque transfer.

    How far are these screws threaded along the shank?

    This product is longer than 1 inch, so it is threaded two-thirds from the bottom of the screw, which leaves an upper shank section to help draw materials together.

    What does the Type 17 auger point do on this screw?

    The Type 17 auger point is designed to cut into the material as the screw starts, which supports easier starting and more accurate placement at the mark.

    Why is case hardening important on this assembly screw?

    The screw is case hardened, giving it a hardened outer layer that supports the head and threads under driver torque during repeated installation work.

    What finish does this Wurth screw have?

    This Wurth assembly screw has a black finish, which provides a dark head color where the fastener remains visible on dark components.

    Choose This Screw For Consistent Assembly Results

    The #8 x 1-1/2 flat head assembly screw with square drive, coarse threads, and a Type 17 auger point gives installers a repeatable fastener for draw-tight joints. The case hardened construction and black finish support production driving and clean visible results on dark workpieces.
