Thread-Cutting Screws

Product detail · Updated 10 October 2026

Product and assembly brief

A thread-cutting screw cuts its mating thread during assembly in a prepared receiving hole. Its cutting grooves and thread end are part of the identity,not decorative details. Keep it separate from chipless thread forming and drill-point screws. Existing head-only tapping references do not establish a cutting screw's thread,lead or receiving-hole requirements.

Product forms and reference names

Choice or field	What to identify
DIN 7513:2016-12	Official identity covers heat-treated hexagon and slotted-head cutting screws with ISO metric threads;the publisher describes cutting flutes from the point towards the head. Specify the exact selected form,not just DIN 7513 or hex head.
DIN 7516:2016-12	Official German description identifies cross-recessed,heat-treated metric cutting screws with grooves inclined to the screw axis and a defined thread end. It is a separate reference from DIN 7513,not automatic head substitution.
Hex and slotted catalogue forms	Bossard BN 1221 identifies hex-head DIN 7513 A;its original alternatives include slotted cheese-head DIN 7513 B. These are catalogue identity examples,not FastenerBridge stock or confirmed material/finish.
Other supplier form or type numbers	Obtain the original catalogue or drawing for any requested type letter/number. Different naming systems or an approximate head reference do not prove identical cutting geometry or interchangeability.

Cutting grooves,lead and thread

The head describes seating and driving;the cutting region and thread determine the mating-thread operation. State metric or other selected thread designation separately from head and drive. Compare the controlled groove direction,extent and thread-end drawing with the required reference. The generic image does not establish standard dimensions,number of flutes or compliance.

Prepared hole and chip space

Bossard's original assembly sequence starts with a drilled or die-cast receiving hole and expressly calls out hole depth and chips. Procurement guidance inferred from this is to identify hole diameter,depth,through or blind construction and chip-clearance/cleanliness requirements together with the selected screw. Do not use nominal screw length as usable engagement or infer a universal pilot-hole ratio.

Receiving material and assembly review

Declare the receiving material and actual condition,section thickness and joint drawing. Review the selected screw's cutting action,head seating,drive access and installation method for that component. Request application-specific assembly limits and acceptance evidence where required. No universal tightening torque,load,reuse or substrate approval is offered here.

Material,treatment and finish

The official reference scopes concern heat-treated screws;the catalogue examples list their own steel,treatment and finish. Do not transfer those catalogue values to all supplied products. Specify the actual material/treatment/coating and relevant inspection evidence,including any embrittlement-risk controls needed for the selected treated/coated screw. Hardness and finish remain quotation facts,not values inferred from the picture.

Reference edition and factual limits

DIN Media identifies both DIN 7513 and DIN 7516 editions 2016-12 as current when checked10October2026;each replaces its 1995-09 edition. Full normative tables and selected-code tolerances were not obtained. Public identity summaries are not certificates of conformity. The DIN 7516 English overview contains unrelated text,so the German publisher description is used for structure;no unrelated claim is carried into this page.

Specification fields

Choice or field	What to identify
Exact identity	Standard and edition,complete form or original supplier code,and controlled drawing revision;no assumed equivalence from a type letter.
Thread and cutting region	Thread designation/pitch,groove direction/extent,thread end and usable engagement from selected drawing.
Receiving component	Material and condition,hole diameter/depth/tolerance,through or blind hole,section and chip clearance;selected application recommendations required.
Head and drive	Head bearing or countersink seat,drive type and access,selected bit/tool interface;no generic compatibility guarantee.
Material and finish	Actual screw material,treatment,hardness and coating requirement,with selected inspection and embrittlement-risk controls where applicable.
Assembly and cleanliness	Approved installation method and limits,chip handling/contamination constraints and validation basis;no universal torque value.
Order and evidence	Quantity,packing,drawing and requested inspection evidence;actual compliance,production,stock and delivery separately confirmed.

Common product questions

Is thread cutting the same as thread forming?

No. The selected cutting screw removes material using cutting geometry;forming displaces material. Do not assume the same receiving hole,assembly window or chip requirements.

Does a cutting screw drill its own pilot hole?

That is not established by a cutting-screw identity. The original catalogue assembly example starts with a prepared hole. A drill-point construction is a separate choice.

Can I order by DIN number or head appearance alone?

Specify edition,complete form,thread,lead/grooves and receiving component. DIN 7513 and DIN 7516 are separate reference scopes;other catalogue type names need their own original specification.

Are the picture and references proof of compliance or supply?

No. The picture is an AI-generated appearance reference;publisher and original catalogue identities do not prove supplied material,geometry,certification or joint performance.

Product references

References checked 10 October 2026 identify structures, not FastenerBridge stock, compliance or brand affiliation. Final requirements follow the selected specification. No normative dimension, load rating or tightening torque is stated.
