    Würth #8 x 1-1/4" Flat Head Assembly Screw Phillips Drive - Sharp Point Coarse Thread Black, 3670000144961 1000 - 1000/Box

    Description

    #8 X 1-1/4 Flat Head Assembly Screw Purpose

    #8 x 1-1/4 flat head assembly screw identifies this screw as a #8 diameter, 1-1/4 inch long fastener, so it suits projects that call out that specific size in drawings or cut lists. The flat head design lets the screw sit flush when set into a countersunk hole, which helps panels pull up tight and gives a clean, level surface for casework or trim. This screw is described as an assembly screw, tying it directly to cabinet, furniture, and general woodworking build-ups where components need to be drawn together firmly. The sharp point detail means it can bite quickly into suitable materials, so the tip engages without pre-formed threads. The coarse thread description indicates a deeper, more aggressive thread pattern that drives quickly in typical wood-based substrates and holds them together during assembly.

    Black Phillips Assembly Screw Job Advantages

    • The #8 x 1-1/4 inch sizing defines a common build dimension, so installers can match this screw to layouts that specify that exact length and gauge for consistent fastening.
    • The flat head style allows the head to sink into countersunk holes, so workpieces can seat firmly together without a proud fastener head interrupting the surface.
    • The Phillips drive design pairs with #2 Phillips drive bits, so crews can use standard bits they already run in drivers for straightforward driving and reduced bit change time.
    • The sharp point feature lets the screw start cutting into the material as it turns, so the thread can establish grip without relying on pre-formed threads in the joint.
    • The coarse thread configuration creates a strong bite in compatible substrates, so the screw can clamp parts together effectively during cabinet or fixture assembly.
    • The black finish provides a dark head appearance, so the screw can blend visually in darker applications where exposed heads need to be less noticeable.

    Threading And Drive Details For Installation

    The note that 3/4 inch and 1 inch lengths are threaded fully while all other sizes are threaded two-thirds from the bottom explains how this series is configured across its range, so buyers can understand that the 1-1/4 inch size belongs to the partially threaded group within that family. The reference to case hardened construction indicates the screw has been hardened, so the material is prepared for driving loads typical of woodworking assembly. The specification that it uses #2 Phillips drive bits means installers can plan to use that common bit size, which streamlines setup for powered drivers in the shop or on site.

    Using This Wurth Screw In Woodworking

    Where This Assembly Screw Fits Best

    The designation as a flat head assembly screw connects directly to tasks such as cabinet boxes, furniture frames, and similar casework where flush-head fastening is important, so builders can use it in joints that rely on tight panel contact. The #8 gauge and 1-1/4 inch length give a moderate penetration depth through typical face frames, stretchers, or panel seams, which suits many interior woodworking joints that do not call for extra-long fasteners. Because the sharp point and coarse thread combination is specified, the screw is suited to fastening into materials where aggressive bite is desirable, such as wood-based components in shop-built projects. The black finish gives the head a dark appearance, which can help when the head will remain visible on dark surfaces or hardware where a lighter head might stand out.

    Details That Support Consistent Assembly Results

    The case hardened description indicates the screw has been hardened, so it is built to handle the driving torque typical of powered installation in woodworking assembly lines or jobsite work. The flat head configuration works with countersunk pilot holes, allowing the head to pull joint members together tightly while ending up level with the surface, which supports clean fitting for face frames, stretchers, or brackets. The specified use of #2 Phillips drive bits allows installers to standardize on one common bit size for this screw, reducing driver setup steps during runs of repetitive fastening. The threading note that only 3/4 inch and 1 inch lengths in this family are fully threaded, with all other sizes threaded two-thirds from the bottom, positions the 1-1/4 inch screw as a partially threaded option, which is typical in assemblies where the upper shank can slide through one member while the lower threads pull the second piece tight.

    Key Questions About This Wurth Assembly Screw

    What size is the Wurth #8 x 1-1/4 assembly screw?

    The Wurth screw is a #8 diameter, 1-1/4 inch long flat head assembly screw, so it matches applications that call for that specific gauge and length in drawings or cut lists.

    What drive type does this assembly screw use?

    The screw uses a Phillips drive and is specified to work with #2 Phillips drive bits, so installers can run it with standard Phillips driver bits already in their tool setups.

    How is the threading configured on this screw family?

    The screw family notes that 3/4 inch and 1 inch lengths are fully threaded, while all other sizes are threaded two-thirds from the bottom, placing the 1-1/4 inch length in the partially threaded group.

    What does case hardened mean for this Wurth screw?

    The case hardened description indicates the screw has been hardened, so it is prepared to handle typical assembly driving forces in woodworking or similar applications.

    Why is a flat head useful on this assembly screw?

    The flat head lets the screw sit flush in a countersunk hole, so panels and components pull tight together and leave a level surface around the fastener location.

    What is the benefit of the sharp point and coarse thread?

    The sharp point starts cutting as the screw turns and the coarse thread provides strong bite, so the fastener can draw wood-based parts together effectively during assembly.

    Choose This Screw For Sized Wood Assemblies

    The #8 x 1-1/4 flat head assembly screw specification lets buyers match the fastener directly to plans that call for that size, which supports predictable results during cabinet or furniture builds. The combination of sharp point, coarse thread, and #2 Phillips drive lets crews use familiar driving techniques while getting firm pull-together in wood-based components. The black finish provides a dark head appearance when a visible fastener needs to blend with the surrounding material. Selecting this Wurth screw for assemblies that match its gauge, length, and drive type keeps fastening consistent across projects.
