Thread Points

THREAD Styles Guide

There are many type of screws thread. If you do not see what you a looking for below contact us for a quote.

  • Die Point

    One of the least expensive pointing operations applied at time of heading. This operation provides and end chamfer starting with the diameter of the thread. The minimum reduction of the point is approximately 10% below the maximum minor diameter with an included angle of 40 to 50 degree

  • Pinch Point

    An inexpensive method of applying a 40, 60 or 90 degree lead-in point having a slightly rounded contour nut with pinch-of marks on its surface. Used for aligning several sheet or assembling several parts requiring pilot action.

  • Round Point

    A dome-like rounded surface applied to the end of a threaded member in order to offer pressure without disfigurement. Used for adjusting member where friction without cutting action is required

  • Type B Point

    A thread forming screw for use in heavier metal .050 to .200 thick. Larger root diameter fit finer thread pitch for light and heavy sheet metal non-ferrous castings, plastics, impregnated plywoods, asbestos combinations, and other materials.

  • Type U Point

    A thread forming screw-with high Helix thread for driving or hammering into sheet metal, castings, fiber or plastics for permanent, quick assemblies.

  • Type 1 Point

    A thread cutting screw with single flute for general use. Produces a fine standard machine screw thread for field replacement.

  • Type 25 Point

    A thread cutting screw similar to Type 23 point except with course Type B thread. For plastics and other soft materials with large chip clearing and cutting edges

  • Dog Point

    A straight point section reduced in diameter slightly below the root diameter of the thread, usually extending in length about two thirds the diameter of the thread. Recommended for ease in starting, to ensure against stripping fine threaded products, and to increase efficiency along production lines

  • Nail Point

    Usually supplied with an approximate 45 degree included angle having a sharp point and slightly squared surface. Used for impinging or locking against wood or other soft material. Other degrees of included angle and sharpness also available.

  • Cone Point

    A precision forming operation to provide any required included angle. Offers a smooth surface, accurate lengths, and a sharp point which can be produced to any desired contour to fit your particular requirements

  • Type AB Point

    A thread forming screw combining location type point of Type A with thread size and pitch of Type B. Normal Limitations of Type B apply.

  • Type F Point

    A thread forming screw with machine screw thread with blunt taper point, having multiple-cutting edges and chip cavities. For heavy gauge sheet metal, aluminum, zinc and lead die castings, cast iron, brass and plastics.

  • Type 17 Point

    A thread cutting screw for wood with a course tapping screw thread and a special long sharp point fluted to capture chips

  • Self Drilling Point

    With special drilling points - lengths - diameter that will drill through 1/4 inch metals. Eliminated all hole preparation - drills faster than a drill. No punching, drilling or tapping required. Reduces die costs

  • Rolled Point

    An efficient method of producing pointed long stud or long screws with an end chamfer similar to the Die Point. The last thread and a half is slightly cupped by the thread roll-over operation.

  • Cupped Point

    A special cup section supplied on the end of the threaded member having a depression in the end to reduce the area in contact with the surface which increases its holding and locking power under pressure.

  • Type A Point

    A thread forming acre for use in thin metal .015 to 050 thick. Used with drilled, punched or nested holes in sheet metal, resin impregnated plywood, asbestos combinations, among others. Not recommended for new designs.

  • Type C Point

    A thread forming screw with either course or fine pitch machine screws threads and a blunt taper point. Eliminates chips and permits replacement with standard screw in the field. Higher driving torque required. Usable in heavy sheet metal and die castings.

  • Type FZ Point

    A thread cutting screw with a tapered screw thread with blunt tapered point and multi-cutting edges and chip cavities. For plastics, die castings, metal clad and resin impregnated plywoods and asbestos.

  • Type 23 Point

    A thread cutting screw in the fine thread series offering maximum thread cutting area and excellent chip clearing, with minimum tightening torques.

  • Self Tapping Point

    Produces more secure sheet metal assemblies faster. Used as self-drilling screw or driving through pre-unched holes. Can be used with or without pilot holes. Positive rake "froward cutting edge" drills straight through sheet metal at peak speed. Perfectly mated threads increase strip and back out pressures.
