About Us: All Holo-Krome products are Made in the USA and used

in a wide variety of market applications which demand high quality,

high strength precision components. Since its formation in 1929,

Holo-Krome has been at the forefront of fastener development and

innovation. In 1930, Holo-Krome invented and later patented the first

practical cold heading process for mass producing high tensile strength

alloy steel socket screws. As you browse through our catalog, you will

see Holo-Krome manufactures and stocks a full line of standard, high

quality socket screw products. In addition to the standard product

line, Holo-Krome manufactures semi-standards, special fasteners and

cold headed parts.

Product Number Code: All standard products have an assigned

Product Number Code shown on the boxes for ease in ordering and

inventory control. All products are sold in full packages only.

Special Products: Products not in the catalog can be quoted on

request. Blueprints and specifications should accompany your request.

Shipments: Holo-Krome will attempt to ship in accordance with your

method of shipment and carrier will be at our sole discretion.

Certifications: On request, using a lot number stamped on the outside

of the Box, and or the Holo-Code® on the head of the capscrew, Holo-

Krome can certify the chemical analysis, the raw material supplier and

the mechanical/dimensional properties of the product.

Product Plating & Modification: Holo-Krome shall not be responsible

for products plated or modified in any manner not under its control.

Allowance - An intentional difference in the dimensions of mating parts. It is the minimum clearance of the maximum

interference which is intended between mating parts. It represents the condition of the tightest permissible fit, or the largest

internal member mated with the smallest external member.

Examples:

A 1/2-13 American National Coarse Thread.

Minimum pitch diameter of nut (2B). . . . . . . . . . . . . . . . . . 0.4500

Maximum pitch diameter of screw (2A) . . . . . . . . . . . . . . . .4485

Allowance (positive). . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 0.0015

Basic Size - The theoretical or nominal standard size from which all variations are made.

Crest Clearance - Defined on a screw form as the

space between the crest of a thread and the root of its mating part.

Finish - The character of the surface on a screw thread or other product.

Fit - The relation between two mating parts with

reference to the conditions of a assembly. For example: Wrench fit; close fit; medium fit; free fit; loose fit. The quality of fit is

dependent upon both the relative size and the quality of finish of the mating parts.

Neutral Zone - A positive allowance (See “Allowance.”)

Limits - The extreme permissible dimensions of a part.

Example :

1/2-13, Class 3A, American National Coarse Thread Series.

The limits are:

Maximum pitch diameter (3A) . . . . . . . . . . . . . . . . . . . . . . . 0.4500

Minimum pitch diameter (3A) . . . . . . . . . . . . . . . . . . . . . . . 0.4463

Manufacturing parts with unusual contour, strength and cost requirements

often becomes uneconomical as material, labor and energy costs escalate.

For many companies, HOLO-KROME® has become the economic design

and manufacturing alternative. The key is metal forming versus metal

removal. We have over 80 years of applied technology experience

in forming metal solutions. For us, tough parts take shape just a

little easier.

Made in the USA products are used in a wide variety of market applications

that demand high-quality, high-strength precision components. In addition

to the standard product line of cap screws, socket shoulder bolts, dowel pins,

socket jam screws, and socket pipe plugs, HOLO-KROME also manufactures

semi-standards, specialty parts and cold-headed parts.

With emphasis on lower cost and higher productivity, more companies are

looking to HOLO-KROME to solve assembly and "tough-to-manufacture"

part problems. If there is a length, material, coating or other criteria you

don't find on our website or in our catalog, we will supply a quotation.

Do you require screw machine parts that have:

• Two or more outside diameters?

• A recess or bore up to 2x diameter in depth?

• A requirement for special material?

Warm or cold heading may be a practical alternative. Shaping metal by

controlled warm or cold forming yields inherently stronger parts. Material

structure is controlled in ciritical stress reas, eliminating the possibility of

tears that are so common with machined parts.

HOLO-KROME can shape various types of material - aluminum and

brasses, austenitic and martensitic stainless, 4000 series alloy steels, all

the way through H-11 and other tool steels - into difficult dimensions

while retaining the metallurgically important property of grain flow.

Tough-to-manufacture parts can be produced at less cost than traditional

methods. With little or no metal removal, savings in material normally

justifies HOLO-KROME's heading process. Our vertically integrated

manufacturing process encompasses many innovative secondary and

finishing operations such as high-speed/proprietary machining, full

capability contour grinding, and precision roll threading up to 2" diameter.

Our finishing operations include a controlled-heat treating department.

Most high-strength alloy parts are automatically conveyed through

furnaces to ensure that specified metallurgical properties are achieved.
