    Thread-Locking Stainless Steel Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Thread-Locking Stainless Steel Phillips Flat Head Screws.
    Our best Phillips flat head screws for keeping parts from coming loose on machinery with mild vibration. They have nylon-patch threadlocker bonded to the threads, saving you the time and mess of adding it yourself. Made of stainless steel, they won't rust or corrode when exposed to moisture and chemicals. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    Length is measured from the top of the head.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Titanium Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Titanium Phillips Flat Head Screws.
    The best of both worlds, these titanium screws are lightweight like aluminum and resist corrosion better than stainless steel. They have a Phillips drive with a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    Length is measured from the top of the head.
    Lightweight Ultra-Corrosion-Resistant Grade 2 Titanium—These screws stand up to strong acids and other harsh chemicals. They're often used in chemical-processing and water-treatment facilities.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.

    Brass Phillips Flat Head Screws

    Image of Product. Front orientation. Flat Head Screws. Brass Phillips Flat Head Screws.
    Conductive and nonmagnetic, these Phillips screws are often used to secure electrical equipment, such as circuit boards, inside enclosures. Made of brass, they also resist corrosion in humid environments. The Phillips drive has a cross-shaped opening in which a driver fits snugly for easy alignment. With four contact points, they withstand more torque than slotted drives, but drivers slip when you apply too much force.
    Length is measured from the top of the head.
    Standard Profile—Standard-profile heads are the most common choice for flat head screws.
