    Tenn-Tex #8 x 3/8" Flat Head Machine Screw Phillips Drive - Blunt Point Fine Thread Zinc, HAR-031 - 1000/Box

    Description

    Tenn-Tex HAR-031 Machine Screw For Targeted Fastening

    Tenn-Tex HAR-031 machine screw describes a Tenn-Tex Plastics, Inc. fastener identified as Manufacturer Part # HAR-031, so installers can match this exact screw when a specification or parts list calls out that number. This #8 x 3/8" flat head machine screw Phillips drive fact shows you are working with a #8 diameter, 3/8 inch length screw designed for Phillips drivers, helping standardize driver bits on a job. The flat head detail means the head is shaped to sit down into a compatible countersunk recess, which supports flush fastener heads where a smooth surface is needed. The machine screw description signals that this screw is intended for machine-threaded engagement rather than wood-style threads, aligning it with threaded inserts or tapped metal components in an assembly. The SAP description stating MACHINE SCREW FOR TXT506 links this screw to TXT506-related applications where that callout appears on drawings or parts breakdowns.

    Key Tenn-Tex Screw Details That Support Work

    • The #8 x 3/8" dimension defines a specific diameter and short length, which helps reduce over-penetration in thin components while still providing thread engagement where a compact fastener is needed.
    • The flat head form allows the head to sit down into suitable countersinks, creating a surface that stays level with surrounding material and reducing snag points on hardware or panels.
    • The Phillips drive detail aligns with common Phillips driver bits, so installers can run this screw using standard tools already on site without changing to specialty drive systems.
    • The blunt point design reduces the cutting tip found on sharp-point screws, which suits applications where the screw engages pre-threaded or prepared holes rather than self-starting into wood fibers.
    • The fine thread description indicates closely spaced machine-style threads, supporting engagement in matching fine-thread components where a machine screw connection is required.
    • The zinc reference indicates a zinc presence on the screw, which provides a recognizable bright finish that helps visually distinguish this fastener from other plain steel screws during layout and assembly.

    Installation Characteristics Of This Phillips Machine Screw

    This #8 x 3/8" flat head machine screw Phillips drive uses a Phillips drive pattern, so installation follows a centered, self-aligning bit profile that many powered drivers support. The flat head style is suited to countersunk holes in mating parts, giving the head a shaped seat for more even bearing on the surface under the head. The blunt point fine thread zinc configuration means the screw expects engagement with fine-thread components or tapped holes instead of cutting into unthreaded wood, which directs how holes are prepared in shop or field work. The zinc mention provides a predictable surface for driving, which helps maintain bit grip during installation when matched with an appropriate Phillips bit size.

    Using This Machine Screw In Hardware Assemblies

    Where This #8 x 3/8 Flat Head Screw Fits

    The Tenn-Tex #8 x 3/8" flat head machine screw Phillips drive details support use where a compact screw length is needed around hardware or fittings. The MACHINE SCREW FOR TXT506 wording in the SAP description connects this screw to TXT506-designated components, guiding its role in those assemblies when that wording appears. As a product in the Fasteners|Screws category and Screws product class, it fits workstreams that rely on screw-based fastening rather than rivets or nails. The blunt point and fine thread characteristics suit applications where the mating part presents machine-style threads or inserts, helping the screw align with the prepared female threads without needing a sharp, cutting tip.

    Why HAR-031 Details Matter For Repeatable Results

    The specific HAR-031 identifier allows foremen, buyers, and installers to call out or reorder the same Tenn-Tex Plastics, Inc. screw, supporting consistent assembly performance across multiple builds using identical fasteners. The #8 x 3/8" sizing keeps the length short, which helps manage stackups where excessive screw length could interfere with internal clearances. The flat head design helps ensure that once driven into a correctly formed countersink, the head will sit down into the recess, supporting assemblies that depend on a flatter exterior face. The Phillips drive interface fits common Phillips driver bits, which supports repeatable torque application using standard fastening tools throughout a project. The fine thread and blunt point description guides the expectation of threading into prepared or matching fine-thread components, which contributes to a more predictable clamp when the correct mating threads are present. The zinc reference provides an identifiable look and surface, which assists in visually verifying that HAR-031 screws are being used wherever TXT506-related instructions specify this machine screw.

    Common Questions About Tenn-Tex HAR-031 Screw Use

    What does the Tenn-Tex HAR-031 part number identify?

    The Tenn-Tex HAR-031 part number identifies a #8 x 3/8" flat head machine screw Phillips drive, so buyers can specify this exact screw when matching drawings or TXT506-related documents.

    How is this #8 x 3/8 machine screw typically driven?

    This #8 x 3/8" flat head machine screw Phillips drive uses a Phillips drive pattern, allowing installation with standard Phillips driver bits used on many screw guns and hand drivers.

    Where does the MACHINE SCREW FOR TXT506 wording apply?

    The MACHINE SCREW FOR TXT506 wording in the SAP description associates this screw with TXT506-related applications where that designation is specified on parts lists or job references.

    Why is the flat head design important on this screw?

    The flat head design on this screw lets it seat into a countersunk recess in the mating material, producing a surface where the screw head sits down and stays more level.

    What does blunt point fine thread indicate for this screw?

    The blunt point fine thread description indicates a machine-style thread for engaging matching fine-thread parts, rather than a sharp-point pattern for starting into wood without prepared threads.

    How does the zinc detail help during selection?

    The zinc detail gives this screw a recognizable appearance compared to plain steel screws, helping crews visually pick the Tenn-Tex HAR-031 fastener specified for TXT506-related assemblies.

    Choose HAR-031 When TXT506 Screws Are Specified

    The Tenn-Tex #8 x 3/8" flat head machine screw Phillips drive with blunt point fine thread zinc is identified as MACHINE SCREW FOR TXT506, aligning it with TXT506-named applications that call out that wording. The HAR-031 part number and #8 x 3/8" sizing help purchasing and installation teams standardize on one precise screw where machine-thread engagement, a flat head profile, and a Phillips drive pattern are required by the project. Selecting this Tenn-Tex Plastics, Inc. screw under the HAR-031 identifier supports consistent fastening whenever TXT506-related drawings, job notes, or parts schedules specify this machine screw.
