  • Brass Molded-In

    As an alternative to SPIROL’s standard inch Molded-In Inserts (Series 63 (Through-Hole) and Series 65 (Blind End)) manufactured from aluminum, SPIROL has a line of non-stocked Molded-In Inserts manufactured from brass. The Series 40 is symmetrical and has a hole through the entire length of the Insert, and Series 44 is the same body style in a blind-ended version. Unlike SPIROL’s standard series of aluminum Molded-In Inserts, these non-stocked series are made from free-machining brass which may be required for some applications exposed to a galvanic corrosive environment. These Brass Molded-In Inserts are made-to-order in inch thread sizes ranging from 4-40 to 3/8-16.

  • HEAT-ULTRASONIC-STRAIGHT-INSERTS

    SPIROL’s Series 27 and Series 28 were designed to be post-mold installed with heat or ultrasonics into straight holes with a 1° maximum (included) draft angle. These Inserts are almost identical to the standard Series 29 Symmetrical and Series 30 Headed Insert offering, yet they have a slightly reduced center knurl diameter to minimize stress in plastic applications with a thin walled boss. The Series 27 is symmetrical for ease of orientation. The Series 28 has the exact same body style as the Series 27 - with the addition of a head for more bearing surface for the mating component to prevent jack-out. The Series 27 (symmetrical) and Series 28 (headed) Inserts are made-to-order in inch thread sizes ranging from 2-56 to 5/16-18.
