FM FASTENER

Makarpura, Vadodara, Gujarat

An externally threaded fastener with metric threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and a hexagonal recess. Generally manufactured in accordance with DIN Standard 912 or ISO Standard 4762.

Ideal for precision assembly work with close tolerances and applications needing a well tooled appearance. Supplies greater tensile strength than equivalent sizes of hex cap screws while requiring less surface area or counter-bore since the fastener is internally wrenched.

Has wings which allow the nut to be manually turned.

Used when a part is frequently assembled and disassembled by hand.

All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc.

A four-sided, internally threaded fastener with a flat bottom side and a chamfered, washer-crowned top.

Square nuts are usually provided with a square bolt and used heavily in the utility and pole line industry.

Designed for use with square bolts.

All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc.

A six-sided nut with a nylon-filled collar at its back end and metric thread pitch. When a bolt or screw reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the fastener when it is subjected to vibration. Generally manufactured in accordance with DIN Standard 985.

All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc.

A six-sided, double chamfered nut that is available in various widths and lengths.

Hex couplers are used to connect two pieces of threaded material. Hex and heavy hex couplers are threaded right hand. If a right hand-left hand coupler is needed, consider using a sleeve nut.

All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc.

Split lock washers provide greater bolt tensioning for tighter assemblies and provide protection against loosening resulting from vibration. Lock washers can be used with a standard washer to provide uniform bearing surface. These washers are unhardened and intended for general use.

looks like a hex nut with an acorn-shaped top.

used to cover exposed, dangerous bolt threads or to add a finished appearance

all nuts are available in 304, 304l, 316, 316l , h.t gr. 8 , 10 , etc.

Has a similar thread design as a metric socket head cap screw. However, the dome-shaped head is wider and has a lower profile than a metric socket head cap screw. Generally manufactured in accordance with ISO Standard 7380.

Used when a wider bearing surface or a smoother, more finished appearance is desired. Button head cap screws do not afford the strength of socket head cap screws and are designed for light fastening applications. They are not recommended for critical, high-strength applications.

A headless screw threaded the entire length, with a hexagonal drive at one end and a point at the other end (e.g., cup, half dog, oval, flat, and cone).

Used for internal wrenching and where frequent disassembly or adjustment occurs.

Washers provide a smooth bearing surface and are used under the head of a bolt and / or a nut. Flat washers are covered under the DIN 125 A / DIN 125 B standards. These washers are unhardened and intended for general use.
