QUICK SELECTION GUIDE3QUICK SELECTION GUIDETypeApplicationFeatures2Suitable for all high tensile applications. Use stainless for corrosive-cryogenic or elevated for use in parts too thin for std. SHCS; and for applications with angle under the head ensures maximum flushness and sidewall contact. Non-slip Hex socket prevents marring of : Inclined angle under the head varies as follows:BSW & BSF Threads - 90 CUNC & UNF Threads - 82 CMetric Threads- 90 CAbove M20- 60 CLow heads streamline design. Use them in materials too thin to countersink: also for non-critical loading requiring heat treated costly special parts - shafts, pivots, pins, guides, linkages and trunnion mountings. Also standard for tool and die collars, sleeves, gears, knobs on shafts.
