FASTENER HEAD TYPES GUIDE

The head styles list below is provided as an example. Tri Suppli will quote you any style(s) you require.

  • 82 Deg Flat Head

    Supplied to standard dimensions with and 80 deg. and 82 deg. Angle to be used where finished surfaces require a flush fastening unit. The countersunk portion offer good centering possibilities

  • 82 Deg. Oval U/C Head

    This is the standard oval head 80 deg. to 82 deg. countersunk screw with the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths. As illustrated, it will fit a standard counterbore hole and is particularly adaptable flush assemblies in thin stock

    This is the standard oval head 80 deg. to 82 deg. countersunk screw with the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths. As illustrated, it will fit a standard counter-bore hole and is particularly adaptable flush assemblies in thin stock

  • 90-100 Deg Oval U/C Head

    This is the standard oval head 90 deg. to 100 deg. countersunk screw with the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths. As illustrated, it will fit a standard counterbore hole and is particularly adaptable flush assemblies in thin stock

    This is the standard oval head 90 deg. to 100 deg. countersunk screw with the lower one-third of the countersunk portion removed to facilitate production of extremely short lengths. As illustrated, it will fit a standard counter-bore hole and is particularly adaptable flush assemblies in thin stock

  • Fillister Head

    The standard oval fillister head has a smaller diameter than the round head, but is higher with a correspondingly deeper slot The smaller diameter head increase the pressure applied on the smaller area and can be assembled close to flange and raised surfaces. Headed in counterbore dies to ensure concentricity, they may be used successfully in counterbore holes.

  • 82 Deg. Oval Head

    Fully specified as “oval countersunk”, this head is identical to the standard flat head, but possesses, in addition, a rounded, neat appearing upper surface for attractiveness of design

  • Binder Head

    Generally used in electrical and radio work because of its identifying undercut beneath the head, which binds and eliminates the fraying of stranded wire. Offers and attractively designed, medium-low head with ordinarily sufficient bearing surface. Not ordinarily recommended as a Phillips recessed head.

  • Indented Hex

    An inexpensive wrench head fastener made to standard hexagon head dimensions. The hex is completely cold upset in a counterbore die and possesses an identifying depression in the top surface of the head.

  • 90-100 Deg Oval Head

    The special 90 deg. to 100 deg. oval head screw has been developed for application requiring flush surfaces, and is recommended for use in soft materials, to distribute pressure over a larger les angular surface. Very well adapted for use with thin aluminum, soft plastics, etc

  • Bugle Head

    Specialized screw with a bugle head that is designed to attach drywall to wood or metal studs, A versatile construction fastener with many uses. The diameter of drywall screw threads is larger than the shaft diameter. Similar to countersunk, but a smooth progression from the shaft to the angle of the head, similar to the bell of a bugle.

  • Pan Head

    Recommended for new designs to replace round, truss and binding heads. Provides low large diameter head, but with characteristically high outer edge along the outer periphery of the head where driving action is most effective for high tightening torques. Slightly different head contour where supplied with recessed head
