Inch Thread – Brass – Molded-In Inserts Non-Stocked Alternatives

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.

If you would like assistance in selecting the most appropriate Insert for your application, please contact SPIROL for complimentary technical support.

Alternatively, SPIROL’s standard Series 63 Molded-In Inserts are made from 2024 aluminum, a lightweight, lead-free grade and offer superior resistance to torque and comparable pull out.
