In today’s marketplace, component standardization and

shorter lead times have become critical to manufacturers.

To meet that need, we have identified a broad range

of engineered threaded fasteners designed to provide

engineers with the quality of the product line while

enhancing their ability to commonize components and

reduce time to market. While these products are highly

engineered, their availability as standards allows you to

access them faster at highly competitive prices.

•Many products are in-stock for immediate delivery

• Lower costs versus specials

• Fast turnaround on quotes

• Lower in-place costs

• Easier ordering processes

• Shorter lead times

• Assists in part consolidation and standardization efforts

• Smaller minimum order quantities

• Faster access to samples for prototypes and testing

Our broad product line is readily available to meet your

needs around the world. While the product offering in

this catalog is extensive, virtually all of the products

shown here can be customized to meet the needs of

your application.

Pricing Information

Our competitive pricing, immediate quotes and shorter lead

times offer a number of benefits to manufacturers. Pricing

for all products in this catalog is immediately available by

calling 1-800-544-6117, or a STANLEY Engineered Fastening


Delivery Information

Often orders can be shipped within 24 hours of receipt. This

can be particularly critical during the product design phase,

as you now have access to production parts for prototypes

or testing. For those that can’t be shipped immediately, the

manufacturing processes for our Engineered Standards®

allow us to offer much shorter lead times than the market is


Ordering Information

To place an order, find out product availability or locate a

distributor in your area, call 1‑800‑544‑6117. To better serve

you, some orders may be directed to a distributor.

Non-Standard Items


Our manufacturing capabilities allow

us to manufacture products from low

carbon steel, medium carbon and alloy

steel, stainless steel, aluminum, brass,

copper, high technology alloys and other



We offer the complete range of platings.

The most commonly used include

phosphate and zinc. To match your color

requirements, we offer zinc and various

color dichromates or an Acu® Coat™



For a wide range of products, we can

manufacture sizes as small as 1mm in

metric and #000 in inch sizes. For larger

sizes, we can manufacture up to 38mm

or 1-1/2".


We can manufacture .060" – 17"

(2mm – 430mm) under the head.

Head Styles:

Many products are available in a variety

of head styles, including pan, flat, oval,

button, socket head cap, hex washer,

external TORX PLUS

® Drive, trimmed hex,

fillister, 12-point, wafer, truss, binding,

and others as required.

Drive Systems:

For optimal assembly line performance,

we recommend the TORX PLUS® Drive

System. However, we also offer TORX®,

Phillips®, hex, slotted, square, 12-point,

tamper‑resistant and other drive systems.


Our standard tolerances follow IFI, DIN,

ANSI, ASTM, SAE, and other consensus

standards. For applications requiring

tighter tolerances, please contact

a STANLEY Engineered Fastening

applications specialist.

We recognize that all applications are unique and may require fastening solutions that

are not considered standard. Because we offer such extensive manufacturing capabilities,

you can customize the fastener to meet the specific needs of your applications.

Customizable Product Features

Special Features:

Our secondary manufacturing

capabilities allow us to enhance the

fastener to meet your specific needs.

We can add shoulders and perform such

secondary operations as drilling, tapping,

shaving, broaching, grinding, roll

forming, burnishing, knurling, sawing,

and reheading to manufacture to the

shape and style you need.

Point Styles:

We can manufacture a broad range of

point styles, including Acupoint®, header,

blunt, chamfer, gimlet, pilot, pinch,

spherical, dog, and others.


We offer a complete range of captivated

washer styles, including conventional,

special, compression and electrical.


We offer nylon patches, adhesives,

and other locking elements. Since each

application is different, these should

be selected with the consultation of

your STANLEY Engineered Fastening

application engineer.

Heat Treating:

Several types of heat treating are available

to meet desired hardness, strength and

ductility characteristics. They include

through hardening, case hardening,

induction hardening, annealing,

carbonitriding and vacuum hardening.


In order to ensure the optimal fastener

for your application, requirements of

the individual application will determine

the appropriate selection of product

parameters. Our application engineers

are available to provide you with any

design or fastener selection assistance

you may require.
