29、 head. flat head: supplied to standard dimensions with an 80' to 82' angle to be used where finished surfaces require a flush fastening unit. the countersunk portion offers good centering possibilities.round head: not recommended for new design (see pan head). this head was the most universa

30、lly used design in the past.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.fillister head: the-standard oval fillister head has a smaller di

31、ameter than the round head. but is higher with a correspondingly deeper slot. the smaller diameter head increases the pressure applied on the smaller area and can be assembled close to flanges and raised surfaces. headed in counter bored dies to insure concentricity, they may be used successfully in

32、 counter bored holes.binding head (straight side): most generally used in electrical and radio work because of its identifying undercut beneath the head, which binds and eliminates fraying of stranded wire. offers an attractively designed, medium-low head with ordinarily sufficient bearing surface.

33、'not ordinarily recommended as a phillips recessed head-see pan head for better functional design.truss head: also known as oven head, stove head, and oval binding head. a low, neat appearing, large diameter head having excellent design qualities, and as illustrated can be used to cover larger d

38、 removed to facilitate production of extremely short lengths. as illustrated, it will fit a standard counterbored hole and is particularly adaptable to flush assemblies in thin stock.flat head (100' countersunk): this special flat head screw has been developed for applications requiring flush su

39、rfaces, and is recommended for use in soft materials. to distribute pressure over a larger and less angular surface. very well adapted for use with thin aluminum, soft plastics, etc.square shoulder screws: an adaptation of the standard carriage bolt design.possesses a truss head on a square shank wh

40、ich resists rotation when located or, driven into place. this square shoulder may also be staked into place as a permanent fastener. a great many varieties in all screw diameters are available in productive quantities.flat head styles take full advantage of the self-centering feature of the counters
