Würth #8 x 1-3/4" Truss Head Machine Screw, Breakaway Phillips/Slotted Drive - Blunt Point Fine Thread Zinc, 3670000272961 1000 - 1000/Box

Truss Head Coverage And Flush Finish After Break

The Würth #8 x 1-3/4" Truss Head Breakaway Machine Screw is a fine-thread zinc machine screw designed for installations where the fastener head must be removed after the assembly is complete. The truss head's wide, low-profile bearing surface holds the work securely during assembly, then the head shears away cleanly at a controlled break point, leaving a flush or sub-flush finish behind.

Key Features

• Truss head profile provides a wide, low bearing surface that distributes clamping load during assembly before the head breaks away.
• Controlled break-away design shears the head at a calibrated point, leaving the fastener flush or below the surface after installation.
• Phillips/Slotted combination drive accepts a #2 Phillips or a flat-blade driver in the same recess for flexibility in the field.
• Fine thread with blunt point threads into pre-tapped holes or nuts for precise, repeatable engagement.
• Zinc finish provides standard corrosion protection suited to dry indoor installations.
• 1,000 per box supports production volume and repetitive assembly runs.

Where This Screw Fits The Job

Breakaway machine screws are the right choice when the fastener's job ends the moment the assembly is complete. The head provides the clamping and driving grip needed to pull components together and seat them correctly. Once torque reaches the break point, the head shears off and the installation is done. What remains is a headless, flush fastener that cannot be backed out with a standard driver.

The truss head on this version spans a wider footprint than a pan or flat head, which is useful when the mounting surface benefits from broader load distribution during the clamping phase. This matters in thin panel work, hardware attachment to laminate-faced substrates, and any application where a standard head diameter would concentrate stress at the fastener hole. Cabinet installation, fixture mounting, and panel assembly are all well-matched to this head geometry.

Fine thread and a blunt point mean this screw threads into pre-tapped holes or pairs with a nut. It does not self-start in wood or undrilled material. For cabinet hardware, mounting brackets, and any assembly built around a pre-tapped component, that is exactly the right configuration.

Zinc Finish And Indoor Use

The zinc finish on this screw provides solid corrosion protection for dry, interior installations. It is the appropriate choice for climate-controlled shops, cabinet interiors, built-ins, and hardware installations that will not see moisture or exterior exposure. The combination of zinc plating and a fine-thread machine screw profile is a standard configuration for indoor cabinet and fixture work.

The Phillips/Slotted drive adds a practical layer of field flexibility. Both drive types are widely available, and having both in the same recess means the installer is not locked into one bit type. The Phillips recess handles most power-driving scenarios; the slot is there when only a flat-blade driver is at hand.

Production Volume In A 1,000-Piece Box

At 1,000 screws per box, this SKU is sized for shops and installers who use breakaway machine screws regularly. Cabinet production lines, millwork teams, and fixture installers running repeatable assemblies will move through quantity quickly, and the box format keeps the supply organized on the bench or in the truck.
