    Würth #8 x 1-1/4" Flat Head Assembly Screw Phillips Drive - Sharp Point Coarse Thread Lubricated, 3670000182961 7500 - 7500/Box

    Description

    #8 Flat Head Assembly Screw For Woodwork

    #8 x 1-1/4 flat head assembly screw gives you a coarse thread, sharp point fastener for general fastening work where a flat seating head is needed against the material surface. The 1-1/4 inch length fits the range described where all other sizes are threaded two-thirds from the bottom of the screw, so the shank section near the head stays clear of threads to help pull parts together. The coarse thread and sharp point work together to cut quickly into typical woodworking materials so driving time stays predictable. The screw is case hardened, which supports a hard wear surface on the outside while the core remains more forgiving under normal driving loads. The lubricated design lowers driving friction so the #2 Phillips drive bit can transfer torque efficiently without excessive cam-out during repetitive assembly work.

    Key Assembly Screw Details For Daily Work

    • The screw uses a #2 Phillips drive bit, so installers can run it with common Phillips drivers already used on many woodworking jobs, reducing bit changes during repeated fastening.
    • The 1-1/4 inch length falls in the group where sizes other than 3/4 and 1 inch are threaded two-thirds from the bottom, helping parts clamp together without threads running all the way under the head.
    • The coarse thread pattern is designed for fast engagement in typical fastening substrates, so the screw advances quickly and seats the flat head efficiently during assembly work.
    • The sharp point at the end of the screw starts into the material without pre-forming threads, helping the screw bite and track straight as it is driven under normal driving pressure.
    • The screw is case hardened, which provides a hard exterior surface at the threads and head contact points that supports repeated driving in standard assembly conditions.
    • The screw is lubricated, so friction between threads and material is reduced as it is driven, helping torque from the driver translate into consistent seating of the flat head.

    Flat Head Drive And Thread Engagement Details

    The flat head style seats flush against the contact surface, which helps components pull tightly together without a protruding head in applications suited to flat head use. The screw uses a #2 Phillips drive, so common Phillips bits fit directly and the driving interface stays consistent with many existing tools. The sharp point and coarse thread combination allows the screw to start and advance into typical fastening substrates with a cutting action, which supports uniform pull-down of parts. For this 1-1/4 inch size, threading two-thirds from the bottom of the screw leaves an upper shank section without threads, which helps the head area draw the top component snugly against the lower piece when the screw is fully seated.

    Using This Wurth Assembly Screw In Practice

    Where This Flat Head Screw Fits Assembly Tasks

    This Wurth #8 x 1-1/4 flat head assembly screw sits in the fasteners and screws class, so it is oriented toward joining components where a countersunk or flat bearing surface is planned. The flat head design lets the screw settle into a recess or sit flush, which supports applications where a smooth surface is needed across the joint line. The coarse thread and sharp point are suited to fastening into materials where thread cutting by the screw itself is expected, so the screw forms its own hold as it advances. Because the 1-1/4 inch size follows the pattern in which sizes apart from 3/4 and 1 inch are threaded two-thirds from the bottom of the screw, the partially unthreaded upper section lets the head zone slide through the top piece while the lower threads grip the base material for pull-together action.

    Why Drive Style, Hardening, And Lubrication Matter

    The specified #2 Phillips drive means the screw takes a widely used bit style, so drivers across a shop can run the same point without changing over to specialty patterns during a run of fastening work. Case hardened construction creates a hardened shell around the screw body, which helps the threads and head bearing surface resist wear and deformation under typical driving torque and seating pressure. The lubricated surface reduces friction between the screw and the material as it is driven, so torque from the driver tool is focused on advancing and tightening instead of overcoming drag. That combination of case hardening and lubrication supports repeatable driving where the screw seats the flat head firmly while maintaining the Phillips drive recess in workable condition through many uses from standard boxes. For buyers favoring volume work, the product is offered in standard boxes of 1,000 and also bulk packs as shown, and it is sold in full box quantities only, which aligns with job environments that consume large counts in ongoing assembly.

    Common Questions About This Wurth Assembly Screw

    What drive size does this assembly screw use?

    This assembly screw uses #2 Phillips drive bits, so standard Phillips drivers can engage the head and transfer torque in typical fastening setups.

    How is the threading arranged on the 1-1/4 inch screw?

    The 1-1/4 inch screw follows the pattern where sizes other than 3/4 and 1 inch are threaded two-thirds from the bottom, leaving the upper section without threads for pull-together action.

    What does coarse thread and sharp point do on this screw?

    The coarse thread and sharp point let the screw cut into the material as it advances, supporting quick starting and strong engagement in typical fastening substrates.

    Why is case hardening important for this assembly screw?

    The screw is case hardened, so the outer surface at the threads and head contact area stays hard under normal driving loads, supporting consistent seating performance.

    How does lubrication affect driving this flat head screw?

    The lubricated screw reduces friction as it is driven, so the driver torque focuses on advancing and tightening the screw rather than overcoming drag in the material.

    What quantities are available for this Wurth screw?

    This Wurth screw is offered in standard boxes of 1,000 and in bulk packs as shown, and it is sold in full box quantities only for volume use.

    Selecting This Screw For Assembly Runs

    This Wurth #8 x 1-1/4 flat head assembly screw combines a coarse thread, sharp point, and lubricated, case hardened body to support repetitive fastening in suitable materials. The #2 Phillips drive aligns with common drivers, and the two-thirds bottom threading pattern on this size helps parts draw together as the flat head seats. For projects that demand consistent pull-down and flush seating using full box quantities, this screw provides a defined set of characteristics that match volume-oriented assembly tasks.
