JCSlim – Low Profile Screws
Our “JCSlim” Ultra-Low Profile screw range is another valuable offering available with unified Threads. Ultra-thin head screws are up to 77% thinner than conventional screw heads which makes possible flat external surface and contributes low-profile design and weight saving.

Wire Thread Inserts
BaerCoil® thread inserts are made from austenitic chromium-nickel steel (stainless steel AISI 304 with a material tensile strength of at least 1400 N/mm²). In production the wire is swaged in cold-form to a rhombic cross-section, which ensures performance and maximum space utilization. With BaerCoil® thread inserts you achieve a better thread connection in regard to wear resistance, thread abrasion, surface finish, corrosion- and heat resistance than with any other single screw connection.

- UNC: 2-56 to 1″
- BSW: 3/16 to 1″
- UNF: 6-40 to 1″

BaerCoil Thread Inserts are also available in Screw Grip type, which have one or more polygon formed windings which have a clamping effect on the flanks of the inserted screw. This forms an elastic and flexible frictional connection. Due to this screw clamping or screw locking effect, it is recommended to use screws with a higher property class (from 8.8 onward) with these inserts.

BaerFix Self Tapping Inserts
BaerFix are self tapping inserts from BAER, Germany, that are designed to cut their own threads as they are being driven into a drilled hole (self tapping). This provides a secure and high strength anchor in the parent material.
BaerFix inserts do not require special tools for tapping.
BaerFix is typically used for thread repair and thread reinforcement.

BAER Threading Tools
Our range of Threading Tools including Taps, Round Dies, etc are also available in Unified and other inch series threads. A tap cuts threads on the inside of a hole, creating a female surface which functions like a nut, to accept a machine screw or bolt.
Taps can also be used to restore an internal thread that has been damaged or to cut a larger thread in the case of severe damage.
BAER Threading tools from Germany are among the highest quality available

Washers
We have a large range of Washers including Plain Washers, Locking Washers, etc suitable for use with unified fasteners available in wide range of materials.
